Question

Plz tell.......................​

Answer 1

sin^2θ/cos^2θ + cos^2θ/sin^2θ = sec^2θ cosec^2θ - 2

LHS:- = tan^2θ + cot^2θ

= (sec^2θ - 1) + (cosec^2 - 1)

= sec^2θ + cosec^2θ -2

hmm well haven't quite figured out how the + sign isn't there between sec and cosec... but i'm pretty sure this is the answer..

hope this helps you!!

pls mark as brainliest!!!
