### Trigonometry Review Game

Sin(45) = sqrt(2)/2

cos(45) = ?

(15 secs)

cos(45) = sqrt(2)/2

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

cos(60) = 1/2

tan(60) = sqrt(3)

tan(90) = undefined

sin(0) = ?

(1 min)

sin(0) = 0

Find the exact value:

sin2 60 + cos 60 =

sin2 60 + cos 60 = 5/4

csc2(30) = 4

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.

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’)
