Trigonometry Review Game

- Do not use a calculator on any of these questions until specified otherwise.

Sin(45) = ?

(1 min)

Sin(45) = sqrt(2)/2

cos(45) = ?

(15 secs)

cos(45) = sqrt(2)/2

Sin(45) = cos(45) since they are cofunctions.

cos(60) = ?

(1 min)

cos(60) = 1/2

tan(60) = ?

(1 min)

tan(60) = sqrt(3)

tan(90) = ?

(1 min)

tan(90) = undefined

sin(0) = ?

(1 min)

sin(0) = 0

sin2 60 + cos 60 =

sin2 60 + cos 60 = 5/4

csc2(30) = ?

csc2(30) = 4

Describe the co function theorem and give an example.

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) = ?

Cot(64.8) = .4706

Find the cofunction for the following. Keep your answer in degrees and minutes.

Csc(63o 14’) = ?

Find the cofunction for the following. Keep your answer in degrees and minutes.

Csc(63o 14’) = sec(26o 46’)

81o 9’ – 43o 47’ = ?

81o 9’ – 43o 47’ = 37o22’

Csc(x) = 1. 6734

X = 36.7o

The rest of the test are right triangle problems.
