Use the given function values and the trigonometric identities to find the exact value of each individual trigonometric function.

Question

Given Function: sin 60 degrees= (squareroot 3)/2, and cos 60 degrees= 1/2

Find a) sin 30 deg

b) cos 30deg

c) tan 60 deg

d) cot 60 deg

Answer 1

The easiest way to do this problem is to draw a 30-60 right triangle and label the sides

(hypotenuse=2, short side =1 and long side=(1/2)√3)

Then read off your answers immediately from the figure...remember the 60º angle is opposite the longer leg!
