• 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:

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
