Cos thitha . Tan thitha =sin thitha prove this

1.	Cos thitha . Tan thitha =sin thitha prove this
Answer» Lhs = cos theta ×sinTheta/cos theta (since tan theta =sin theta /cos theta ) =now cancel cos theta and cos theta =sin thetha Therefore lhs =rhs Proved Cos theta.tan theta=sin theta. Cos theta.sin theta/cos theta{tan theta=sin/cos} so sin=sin
