If `theta in (pi//4, pi//2)` and `sum_(n=1)^(oo)(1)/(tan^(n)theta)=sin theta + cos theta`, then the value of tan `theta` is

If tan theta+sin theta=m and tan theta-sin theta=n

If tan theta=(m)/(n), then find the value of cos theta and sin theta.

If tan theta=(m)/(n) then (m sin theta+n cos theta)/(m sin theta-n cos theta) =

Solve tan theta tan4 theta=1 for 0

2 cos (theta - pi //2) + 3 sin (theta + pi//2) - (3sin theta + 2 cos theta ) = ? A. cos theta - sin theta B. sin theta - cos theta C. sin theta + cos theta D. cot theta - tan theta .

If f(theta)=sin(tan^(-1)((sin theta)/(sqrt(cos2 theta)))), where -(pi)/(4)
