Answer 2

$\mathtt{Question : (1 + cot^2\theta)(1 - cos\theta)(1 + cos\theta)}$

$\mathtt{\implies ( 1 + cot^2\theta)(1 - cos^2\theta)}$

$\mathtt{\implies ( 1 + cot^2\theta)(sin^2\theta)}$

$\mathtt{\implies sin^2\theta + (cot^2\theta)(sin^2\theta)}$

$\mathtt{\implies sin^2\theta + \bigg(\dfrac{cos^2\theta}{sin^2\theta}\bigg)(sin^2\theta)}$

$\mathtt{\implies sin^2\theta + cos^2\theta}$

$\mathtt{\implies 1}$
