MathematicsWhat do we need to know?

We need to have basic understanding of:

• Basic Algebra - cross-multiplication, cross-addition and -subtraction, averaging, powers and roots, bracketing, percentages, inverse calculation and vectors.

• Basic Trigonometry – Triangles, Ratio’s, Pythagoras.

• Basic Interpolation.• How to operate the Navigation Computer and

Scientific Calculator.

The Myth – “this is difficult…”

• If you passed Mathematics up to Grade 10 standard grade, you have covered everything you will need.

• There is NOTHING in the CAA theory syllabus, that is as difficult as passing a current Grade 12 Higher Grade Mathematics' exam – go try one….

SA Grade 12 formulas in 2008……

That Being Said….

• You have to know the basics WELL.• You have to know your calculators WELL.• You have to stay CURRENT.• You have to show enough RESPECT for the

basics required.• The CPL/ATPL exam is quite a lot of work –

about the same volume as the first 3 month’s of Engineering studies at University. If you are not on top of the required mathematics, you will waste time.

Trig Example: You are taking off from a runway, with a hill 300’ high, 6000’ from the threshold. What angle of climb must you maintain to clear the hill?

tan c = b/a

And y=300’ and x=6000’

Tan x = 0.05

Divide by tan same as inverse (or cot, or tanˉ¹)

Thus c = 2,86º

Functions

A fraction is an ordered pair of whole numbers, the 1st one is usually written on top of the other, such as ½ or ¾ .

The denominator tells us how many pieces the whole is divided into, thus this number cannot be 0.

The numerator tells us how many such pieces are being considered.

• Variable – A variable is a letter or symbol that represents a number (unknown quantity).

• 8 + n = 12

• A variable can use any letter of the alphabet.

• n + 5

• x – 7

• w - 25

An Equation is like a balance scale. Everything must be

equal on both sides.

10 5 + 5=

When an amount is unknown on one side of the equation it is

an open equation.

7 n + 2=

When you find a number for n you change the open equation to a true equation. You solve

the equation.

Simple Algebra• Remember Rules:

• The sum of two positive numbers is always positive.

• The sum of two negative numbers is always negative.

• Multiplication/Division of two positive numbers is always positive.

• Multiplication/Division of two negative numbers is always positive.

• Multiplication/Division of a positive and a negative number is always negative.

Addition and Subtraction

26+(-38)-(-55)+(-61)-(23) =

-41

On the calculator – type it all without the brackets….

Powers and Roots

2 x 2, same as 2², same as 2 to the power of 2, same as 4.

The root of 4, same as √4, same as 2.

On the calculator:

2x², enter = 4

√4, enter = 2

Inverse operation the opposite operation used to

undo the first. • 4 + 3 = 7 7 – 4 = 3• 6 x 6 = 36 36 / 6 = 6• Use “xˉ¹” on you calculator.

Parentheses and Brackets)

Use brackets when you want to do certain calculation before the rest:

b² = 60² - (35000÷6080)²

b² = 3566,8. Now press √ and

b = 59,72

C = 2 x ((9÷3) + (4+3)²)

C = 2 x (3 + 49)

C = 104

Order of Algebraic Operation:

“PEMDAS”Solve in the following sequence:

• P for solving Parentheses(or brackets)

• E for solving Exponents next

• MD for Multiplication and Division next

• AS for Adding and Subtracting next.

Example:

• y = ((4³ + √((3+27) – (25÷5))) ÷ 3) + 273

• P is y = ((4³ + √(30 – 5)) ÷ 3) +273 And y = ((4³ + √25) ÷ 3) +273• E is y = ((64 + 5) ÷ 3) +273• MD is y = (69 ÷ 3) + 273• AS is y = 23 + 273 = 296

Prove it by typing the whole equation into your calculator at once….

Solving Addition and Subtraction Equations

Procedure

• Isolate the variable by performing the inverse operation on that variable.

• The inverse of subtraction is adding. The inverse of adding is subtracting.

• Perform the same operation on the side of the equal sign that does not have a variable.

Example

y + 13 = 25

We want to get the y by itself. Perform the inverse operation. The inverse of adding is subtracting.

- 13 Do the same operation on the other side of the equal sign.

- 13

y = 12

Check the answer in the original equation.

y + 13 = 2512 + 13 = 25

25 = 25

Example 2

k – 12 = 4To get k by itself, we perform the inverse operation. The opposite of “minus 12” is “plus 12.”

+ 12 + 12

k = 16

Check

k – 12 = 4

16 – 12 = 4

4 = 4

Solving Multiplication and Division Equations

Procedure

• Isolate the variable by performing the inverse operation on the number that is attached to the variable.

• The inverse of multiplication is division. The inverse of division is multiplication.

• Use the “Golden Rule.” Perform the same operation on the other side of the equal sign.

Example

m ÷ 3 = 10The inverse of division is multiplication. x 3Repeat the operation on the other side.

x 3

m = 30

Check. Use the original equation.

m ÷ 3 = 1030 ÷ 3 = 10

10 = 10

Example 2

7b = 105The inverse of multiplying is dividing.

÷ 7 ÷ 7

b =10571

735

5

350

15

Check

7b = 1057(15) = 105

105 = 105

Cross MultiplicationMoving the variable around in a function, until the

unknown variable is isolated.

Example: In a² = b² + c², if we have to

solve for c we have to isolate it on one side of the equal sign.

Important: What you do on one side of the equation has to be done on the other side.

Thus: a² = b² + c² - b² leaves c² isolated,

but then we have to subtract b² on the left side of the equation as well:

a² - b² = c²

SIN B =

And solving for B in the following function:

b x x b Something divided by itself = 1

• Remember “of” means multiply in mathematics.•“Per” means division in mathematics.

Solve the Problems3a = 21

To solve a, divide both sides by 3:

a = 7

b + 17 = 59To solve a, subtract 17 from both sides:b = 42

c – 22 = 100To solve c, add 22 to both sides

d = 505To solve for d, multiply both sides by 5d = 250

Exponents

Vocabulary

exponent – the number of times a number is multiplied by itself.

base – the number that is being multiplied.

83base

exponent

This is read “8 to the 3rd power” or “8 cubed.”

It means 8 x 8 x 8.

Evaluating Exponents

25= 2 x 2 x 2 x 2 x 2 = 32

63 = 6 x 6 x 6 = 216

1.34 = 1.3 x 1.3 x 1.3 x 1.3 = 2.8561

Exponents with a base of 10

• Any multiple of ten can be expressed as an exponent with a base of ten.

• The base is 10. The number of zeroes gives us the exponent.

• Example: 100 = 102

• 10,000 = 104

1,000,000 = 106

Writing in Expanded Form Using Powers of 10

• First, write the problem in expanded form.

• Then, change each term to a multiplication of the value and its place.

• Change the place values to exponents with powers of 10.

Example 7, 946

7, 000 + 900 + 40 + 6(7 x 1,000) + (9 x 100) + (4 x 10) + (6 x 1)

7 x 103 + 9 x 102 + 4 x 101 + 6

Percentages

Simply a fraction of 100 (meaning “cent)

Examples:

•1/3 = 33.33% (1÷3x100)

•¾ = 75% (3÷4x100)

•1½ = 150% (3÷2x100)

•15% of 3267 = 490

•230 expressed as a % of 430 = 230÷430x100 = 53,5% On the calculator –

use “shift, %” to do it faster.

Percents Have Equivalents in Decimals and Fractions

Finding a Percent of a Number

Using a Proportion

• Set up a proportion that uses the percent over 100.

• Cross multiply to write an equation.

• Solve the equation.

To set up your proportion, think, “IS over OF equals PERCENT over 100.”

Example – What is 20% of 30?

= 20100

part

whole30x

=100x 30(20)=100x 600

100 100=x 6

Using a Decimal

• Change the percent to a decimal.

• Multiply that decimal by the number you are finding the percent of.

Example – What is 18% of 70?

18% = 0.18

0.18 x 70 = 12.6

Vocabulary

• A percent is a ratio that compares a number to 100. It means “per 100.”

• 49 out of 100 is 49%.

Writing Percents as Decimals

• Imagine a decimal point in the place of the percent sign, and move the decimal two spaces to the left (the same as dividing by 100).

26% .26

40% .40 .47% .07

Writing Percents as Fractions• Place the percent in a fraction with a

denominator of 100.• Simplify the fraction.

26% 26100

Included %When asked to work out the % of reserve fuel when it’s already included in the total given, care must be taken with the mathematics:

Example:

We have 11 500 Lt of fuel which include 15% reserve – how much fuel do we have available without using the reserve fuel?

If we started with 10 000 Lt and then had to add 15% reserve it means:

10 000 x 15% = 1500 + 10 000 = 11 500 Lt total fuel.

To reverse the calculation (how much fuel do we have without the 15%), we have to divide the total with 1.15 (or 115%).

Or 11 500 ÷ 1.15 = 10 000 Lt

Averages

Simply add all the quantities and divide it by the number of quantities

Example:

7, 11, 14, 8, 3, 26

means

(7 + 11 + 14 + 8 + 3 + 26) ÷ 6 = 11.5

Hint

• If you don’t see a negative or positive sign in front of a number it is positive.

9+

Rounding of Decimal Numbers

• When the digit to the right of the last retained digit is 5 or greater, round up by 1

• When the digit to the right of the last retained digit is less than 5, keep the last retained digit unchanged

Example:

23.46 becomes 23.5

And 2.1938 becomes 2.2

Note: Only do rounding at the

final calculation…..

Ratios• A comparison of two numbers

• Can be expressed as:– a fraction– A colon (:)– The word “to”

Example:

A gear ratio of 5:8 can be express as:

⅝ or 5:8 or 5 to 8

Ratios in Aviation

• Compression Ratio• Mach Number• Aspect Ratio• Air-Fuel Ratio• Glide Ratio• Gear Ratio• Interpolation• Trigonometry• Map Scales

No Unit of Measure….

i.e.: cm, lt or nm, etc.

Ratios

• A ratio is a comparison between two numbers by division.

• It can be written in three different ways:

5 to 25 : 2 5

2

Equal Ratios

• When two ratios name the same number, they are equal. It’s like writing an equivalent fraction.

20 : 30Equal Ratios:

10 : 15 2 : 3 80 : 120

Example:If the cruising speed of an airline is 200knots and its maximum speed is 250knots, what is the ratio of cruising speed to the maximum speed?• Solution:

• First express the speeds as a fraction:– Or Ratio =

• Then reduce fraction to smallest terms:– Or Ratio = = or 4 to 5, or 4:5

Angles

Vocabulary

• An angle has two sides and a vertex.

• The sides of the angles are rays. The rays share a common endpoint (the vertex)

• Angles are measured in units called degrees.

Types of Angles

When lines intersect to form right angles, then they are classified as perpendicular lines.

Measuring Angles

• Place the center point of the protractor on the vertex of the angle and turn the protractor so that one side lines up with 0 on the inner scale.

Measuring Angles (strategy 2)

• Place the center point of the protractor on the vertex of the angle. Note where both rays cross the protractor. Subtract the two numbers (from the same scale)

Property of triangles

• The sum of all the angles equals 180º degrees.

Classifying Triangles

Classifying by Angle

•Acute triangles have three acute angles.

•Obtuse triangles have one obtuse angle.

•Right triangles have one right angle.

Classifying by Sides

•Equilateral triangles have three congruent sides.

•Isosceles triangles have two congruent sides.

•Scalene triangles have zero congruent sides.

Finding Missing Angles•The three angles of a triangle always add to 180°.

•Use a variable to stand for the missing angle and set an equation equal to 180.

x + 49 + 47 = 180x + 96 = 180 – 96 = -96

x = 84

How to Mind Map1. Use just key words, or wherever possible images. 2. Start from the center of the page and work out. 3. Make the center a clear and strong visual image that depicts the

general theme of the map. 4. Create sub-centers for sub-themes. 5. Put key words on lines. This reinforces structure of notes. 6. Print rather than write in script. It makes them more readable and

memorable. Lower case is more visually distinctive (and better remembered) than upper case.

7. Use color to depict themes, associations and to make things stand out.

8. Anything that stands out on the page will stand out in your mind. 9. Think three-dimensionally. 10. Use arrows, icons or other visual aids to show links between

different elements. 11. Don't get stuck in one area. If you dry up in one area go to

another branch. 12. Put ideas down as they occur, wherever they fit. Don't judge or

hold back. 13. Break boundaries. If you run out of space, don't start a new

sheet; paste more paper onto the map. (Break the 8x11 mentality.)

14. Be creative. Creativity aids memory. 15. Get involved. Have fun.

2  Take Guilt-Free Days of Rest.

3  Honor Your Emotional State. Do not study if you are tired, angry, distracted, or in a hurry.

4  Review the Same Day.

5  Observe the Natural Learning Sequence. if you try first to grasp the big picture and then fill in the details, you often have a more likely chance of success.

6  Use Exaggeration. Why do runners sometimes strap lead weights to their legs?

7  Prepare Your Study Environment. For example, do you need special lighting, silence, music, privacy, available snacks, etc.?

8  Respect “Brain Fade.” As you place more information on top, the lower levels become older and less available to your immediate recall. The trick here is simply to review.

9  Create a Study Routine. An effective way to do this is to literally mark it down in your datebook calendar as if you have an appointment, like going to the doctor. For example: “Tuesday 3-4:30 P.M. — Study.

10   Set Reasonable Goals. Set your vision on the long-term dream, but your day-to-day activity should be focused exclusively on the short-term, enabling steps.

11   Avoid the Frustration Enemy. Don’t waste energy blocking, getting upset, and thinking that you’re not good enough — simply keep moving forward at a slower (but un-blocked) pace.
