Cot θ cos θ+ tan θ sin θ
= (cosθ/sinθ)cosθ + (sinθ/cosθ)sinθ
= [cos^3(θ) + sin^3(θ)]/sinθcosθ
Factorize the numerator and simplify.
Hi all I’m stuck again on another trig identity problem , I would be grateful for any help Thanks
Verify the following
Cot θ cos θ+ tan θ sin θ = (cosec θ+sec θ)(1-sin θ cos θ)
I’ve been trying for ages and seem to be going round in circles
Kind regards
