Question

prove that root secant squared theta + cos squared theta is equal to tan theta + cot theta​

Answer 1

In question , if "cosec square theta" is there in place of "cos square theta" then only it can be solved.

if it is not , then question is wrong.

and as you know (tan theta×cot theta)=1 so, I just replaced 1 with it in 4th step.
