Question

pls anyone tell me the answer to the question in the picture​

Answer 1

Step-by-step explanation:

cosec theta+ cot theta = k

1 + cos theta = k

sin theta. sin theta

1+cos theta = k sin theta

(1+cos theta)^2 = k^2 sin^2 theta

(1+ cos theta )^2 = k^2(1- cos^2 theta)

(1+cos theta)^2 = k^2(1+cos theta)(1-cos theta )

(1+cos theta)= k^2- k^2 cos theta

k^2 cos theta+cos theta = k^2 -1

cos theta (k^2+1) = k^2 -1

cos theta= k^2-1/k^2 -1
