Question

5. Prove the identity:
(cot x sin x)(sec x – cos x) = sin2x

Answer 1

Please simplify and explain step by step

Answer 2

we know that cotx = cosx/sinx so cosx/sinx * sinx = cosx
So we have cosx(secx - cosx) & we know that secx = 1/cosx
so just distribute cosx to the braket , what do you get ?

Answer 3

Correct !

Answer 4

yes but can you show me the calculations that go next to what I wrote?
