Question

CAn some one please explain how to do this question; If f(x)=tan5x-sin2x, find f(pi/6)

Answer 1

replace each x with pi/6

Answer 2

Then refer to your unit circle to find the value of tan(5pi/6) and sin(pi/3)

Answer 3

the unit circle?

Answer 4

the question didn't give a unit circle

Answer 5

Ok. then draw an angle of 5pi/6, find the reference angle and find the tangent
P.S. Most problems that use the unit circle don't give one. You are supposed to have one yourself.
