Question

Proved that cos²theta-sin²theta/sin theta cos theta = cot theta - tan theta​

Answer 1

Step-by-step explanation:

cos squared theta minus sin squared theta divided by sin theta cos theta is equals to cos theta minus tan theta

LHS

cos squared theta minus sin squared theta divided by sin theta cos theta

RHS

cot theta is equals to cos theta upon sin theta and Cos theta is equal to sin theta upon cos theta cos squared theta minus sin squared theta divided by sin theta cos theta is equals to LHS

hence proved ...
