Help please ASAP!!!! I NEED CORRECT ANSWERS ONLY FOR BRAINLIEST

nalin [4]

we are given

$tan^2(\theta)(1-cot^2(\theta))$

Firstly , we can distribute tan^2 inside

we get

$=tan^2(\theta)*1-tan^2(\theta)*cot^2(\theta)$

now, we can simplify it

$=tan^2(\theta)-tan^2(\theta)*cot^2(\theta)$

we know that

tan=1/cot

so, tan^2 will get cancelled with cot^2

$=tan^2(\theta)-1$

so, option-C..............Answer
