Question

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

Answer 1

Answer:

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

cross multiplying:-

(1-cos theta )(1+cos theta)=(sin theta )(sin theta)

Here (a+b)(a-b)=a^2-b^2 is used so,

1^2-costheta^2=sin theta^2 1-costheta^2=sintheta^2

By identity 1 sin ^2=1-cos^2
