Question

show that tan theta .sin + cos theta is equals to sec theta,do it step by step then you will be a brainlist by me

Answer 1

Answer:

tanθ.sinθ + cosθ = sinθ/cosθ * sinθ +cosθ

                           = sin²θ/cosθ + cosθ

                           = sin²θ + cos²θ

                                     cosθ

                           = 1/cosθ

                           = secθ

(hence proved)
