Question

if cot theta -tan theta =2cos square theta- one by sin theta and cos theta

Answer 1

Answer:

LHS

Cot theta-tan theta

Cos theta/sin theta-tan theta/cos theta

Cos square theta-sin square theta/sin thetacos theta

Cos square theta-(1-cos square theta)/sin theta cos theta

Cos square theta-1+cos square theta/sin theta cos theta

2cos square theta-1/sin theta cos theta

Hence proved
