Find real values of `theta` for which `(4 + 3i sin theta) / (1 - 2i sin theta)` is purely real.

prove that sin theta + tan theta = (cos theta) / (1-sin theta)

Find dy/dx if : x= 3 cos theta - 2 cos^3 theta , y= 3 sin theta - 2 sin^3 theta

Find the most general value of theta which satisfies the equation sin theta =-(1)/(2) and tan theta =(1)/(sqrt(3))

If tan theta = (4)/(3) , then 3sin theta - 4 cos theta =

(14) If sin theta =1, then find cot theta =…….

Prove that : (ii) 1/(1+ sin theta)+(1)/ (1-sin theta) = 2sec^2 theta

If sin^2 theta=1/4 , then value of theta is

4sin(pi/3+theta)sin(pi/3-theta)=

Simplify the following. (Cos theta - i Sin theta)^7 / (Cos 2theta - i Sin 2theta)^4
