Trigonometry Review Game
• Do not use a calculator on any of these questions until specified otherwise.
Sin(45) = ?(1 min)
Answer:
Sin(45) = sqrt(2)/2
cos(45) = ?(15 secs)
Answer
cos(45) = sqrt(2)/2
Sin(45) = cos(45) since they are cofunctions.
cos(60) = ?(1 min)
answer
cos(60) = 1/2
tan(60) = ?(1 min)
answer
tan(60) = sqrt(3)
tan(90) = ?(1 min)
answer
tan(90) = undefined
sin(0) = ?(1 min)
answer
sin(0) = 0
Find the exact value:
sin2 60 + cos 60 =
answer
sin2 60 + cos 60 = 5/4
csc2(30) = ?
answer
csc2(30) = 4
Describe the co function theorem and give an example.
Answer:
Answers will vary. Anything to the likes of “If two angles are cofunctions, then the trig function of one angle will equal the cofunction of its complement. Ex: sin30 = cos60” would do.
Ok, now you can use a calculator.
Cot(64.8) = ?
answer
Cot(64.8) = .4706
Find the cofunction for the following. Keep your answer in degrees and minutes.
Csc(63o 14’) = ?
answer
Find the cofunction for the following. Keep your answer in degrees and minutes.
Csc(63o 14’) = sec(26o 46’)
81o 9’ – 43o 47’ = ?
answer
81o 9’ – 43o 47’ = 37o22’
Find x
Csc(x) = 1. 6734
answer
X = 36.7o
The rest of the test are right triangle problems.
