Question

Can you please show these identies proofs?

Answer 1

Answer:

yes it can be prove mate.

1. sin theta = sin theta
2. sin^2 theta + cos^2 theta=1

=> sin theta= √1-cos^2 theta

similarly using the formula ,replace the system and hence you can find the answer.

tan theta=sin theta/ cos theta

so,sin theta=tan theta/√1+ tan^2 theta

hope this much helps you
