Respuesta :

we are given

[tex] tan^2(\theta)(1-cot^2(\theta)) [/tex]

Firstly , we can distribute tan^2 inside

we get

[tex] =tan^2(\theta)*1-tan^2(\theta)*cot^2(\theta) [/tex]

now, we can simplify it

[tex] =tan^2(\theta)-tan^2(\theta)*cot^2(\theta) [/tex]

we know that

tan=1/cot

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

[tex] =tan^2(\theta)-1 [/tex]

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