Question

1+sin theta/cos theta=cos theta/1-sin theta​

Answer 1

Step-by-step explanation:

1+sin theta/cos theta=cos theta/1-sin theta

taking R.H.S

Cos theta/1-sin theta

cos theta/1- sin theta×1+sin theta/1+sin theta

(Taking Rationalisation above)

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

(a-b)(a+b)=a square-b square

cos theta×1+sin theta/ cos square theta

(1-sin square theta=cos square theta)

1+sin theta/cos theta

Hence proved

L.H.S= R.H.S
