Prove the following : sin(90° - A)/cosec(90° - A) + cos(90° - A)/sec(90° - A) = 1

Question

KnowledgeBoat · Accepted Answer

We know that, cos (90 - θ) = sin θ, sec (90 - θ) = cosec θ, sin (90 - θ) = cos θ and cosec (90 - θ) = sec θ. Solving L.H.S. of the equation, we get : Since, L.H.S. = R.H.S. Hence, proved that = 1.
