What Is Cos Minus Theta? [Solved]

For any acute angle of θ, the functions of negative angles are: sin(-θ) = – sinθ cos (-θ) = cosθ

why sine minus theta is minus sine theta || proof of negative angle trignometric identity ||

in this video sajid sir give proof of all negative identity. in which he explain about why sine

cos(-theta)=cos theta proof | cos minus theta is equal to cos theta

In this video, we will prove

Sin(- θ) | Cos(-θ) | Sin minus theta is equal to | Cos minus theta is equal to | tan minus theta is
