What is Calculus?
According to Wikipedia:
Calculus is a branch of mathematics focused on limits, func-tions, derivatives, integrals, and infinite series. . . . It hastwo major branches, differential calculus and integral calcu-lus, which are related by the fundamental theorem of calculus.Calculus is the study of change, in the same way that geome-try is the study of shape and algebra is the study of operations andtheir application to solving equations. . . . Calculus has widespreadapplications in science, economics, and engineering and can solvemany problems for which algebra alone is insufficient.

Section 1.1 – Functions and Their Graphs
Definition
A function f from a set D to a set Y is a rule that assigns a unique(single) element f (x) ∈ Y to each element x ∈ D.

Section 1.3 – Rates of Change and Tangents to Curves
Definition
The average rate of change of y = f (x) with respect to x over the interval[x1, x2] is
∆y
∆x=
f (x2)− f (x1)
x2 − x1=
f (x1 + h)− f (x1)
h, h 6= 0
So we know we can find the slope of the line between any two points Pand Q on a curve. What about the slope of the curve at any givenpoint?
It’s reasonable (and correct, as we’ll see later this semester) to associatethe slope of the line tangent to a point on a curve with the slope of thecurve at that point.

Section 1.4 – Limit of a Function and Limit Laws
Definition
Let f (x) be defined on an open interval about x0, except possibly at x0itself. If f (x) is arbitrarily close to L for all x sufficiently close to x0, wesay that f approaches the limit L as x approaches x0, and we write
limx→x0
f (x) = L.
Definition (formal – as given in Sec. 1.5)
Let f (x) be defined on an open interval about x0, except possibly at x0itself. We say that the limit of f(x) as x approaches x0 is the numberL, and write
limx→x0
f (x) = L,
if, for every number ε > 0, there exists a corresponding number δ > 0 suchthat for all x ,
0 < |x − x0| < δ ⇒ |f (x)− L| < ε.

One common task we’ll have is to find the value of the limit (assuming itexists). To do this we’ll need to make use of ”limit laws”. First, however,we present a few special cases.
f is a constant function, i.e., f (x) = klimx→x0
f (x) = limx→x0
k = k
f is the identity function, i.e., f (x) = xlimx→x0

In addition to our ”limit laws”, there are some theorems that will help usquickly compute limits.
Theorem (Limits of Polynomials)
If P(x) = anxn + an−1xn−1 + · · ·+ a0, then
limx→c
P(x) = P(c) = ancn + an−1cn−1 + · · ·+ a0.
In other words, to compute the limit as x approaches c of a polynomial,simply plug c in for x in the polynomial!

Like we did for polynomials, if we need to compute the limit as xapproaches c of a rational function, we just plug c in for x in both thenumerator and denominator.
Note in the statement of the theorem the phrase ”and Q(c) 6= 0”. If, infact, we DO have Q(c) = 0, there are some techniques we can employ totry to compute the limit. These will be presented by example after wepresent the next two theorems.

Theorem (The Sandwich, or Squeeze, Theorem)
Suppose that g(x) ≤ f (x) ≤ h(x) for all x in some open intervalcontaining c, except possibly at x = c itself. Suppose also that
limx→c
g(x) = limx→c
h(x) = L.
Then limx→c f (x) = L.
Suppose we don’t know to compute the limit as x approaches c of thefunction f . If we know that f is always between two other functions, gand h, whose limits as x approaches c both equal L, then we areguaranteed that the limit as x approaches c of the function f is also L.

”Toolbox” Summary – When computing limx→c
f (x):
first try plugging c in for x
simplify f (x) by canceling common factors, then take the limit
multiply numerator and denominator of f (x) by the ”conjugate”,simplify f (x), then take the limit
when all else fails, make a table of values letting x get closer andcloser to c (from both sides) and see if you can determine if f (x) isapproaching a real number L

f (x) = L means f (x)→ L as x → c from both sides of c
thus, when we say limx→c
f (x) = L, we mean a two-sided limit
a function that fails to have a two-sided limit at c may still haveone-sided limits at c

One-sided limits are related to (two-sided) limits in the following way:
Theorem
A function f (x) has a limit as x approaches c if and only if it has left-handand right-hand limits there and these one-sided limits are equal:
limx→c
f (x) = L ⇐⇒ limx→c−
f (x) = L and limx→c+
f (x) = L.
The ”if and only if” (⇐⇒) in this theorem means:
if limx→c
f (x) = L, then both one-sided limits exist and are equal to L
if both one-sided limits exist and are equal to L, then limx→c
f (x) = L
The power of this theorem is in the second bullet. Let’s see it action.

To prove the theorem we are going to show that both the left-handand right-hand limits are equal to 1.
We’ll employ concepts from algebra, geometry, and trigonometry, aswell as calculus, in the proof.
Recall:
I area of a triangle =1
2bh
I area of a circle = πr2
I radians in a circle = 2π
I area of a sector =θ
2π· πr2 =

2r2θ
I tan θ =opposite

Proof.
area ∆OAP < area sector OAP < area ∆OAT
12 sin θ < 1
2θ <12 tan θ
divide each term by 12 sin θ (a positive #, so inequality signs unchanged)
1 < θsin θ <
1cos θ
take the reciprocal of each term (reverses the inequality signs)
1 > sin θθ > cos θ
Since limθ→0+ 1 = 1 and limθ→0+ cos θ = 1, by the Sandwich Theoremlimθ→0+
sin θθ = 1. Also, since sin θ and θ are both odd functions, sin θ
θ is an
even function, so limθ→0−sin θθ = limθ→0+
sin θθ . Thus, limθ→0
sin θθ = 1.
