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.
