Question details

For this question, we will show how to express trigonometric functions as partial fractions.

(a) Using the tangent half-angle substitution tan(θ/2-t show that 1 -t2 cos(6)1+t 2t t2+1 and sin() (b) Using part (a) express sin(6) cos(e) using partial fractions. You may lave your final answer in terms of t. Hint: You will need to use polynomial division.
