Question

co secant theta minus cos theta whole square is equals to 1 minus cos theta by 1 + cos theta

Answer 1

If you're asking an NCERT book question, I remember the question as:
Prove (cosecx - cotx)^2 = 1 - cosx/ 1 + cosx)

Solution: (1/sinx - cosx/sinx) ^2

= ( 1 - cosx/sinx)^2

= (1 - cosx)^2/ sin^2x

= (1 - cosx)^2/ 1 - cos^2x

= (1 - cosx)^2/ (1 - cosx) ( 1 + cosx)

= 1 - cosx/ 1 + cosx

Hence, proved.
