Cos theta sin pi/2 - theta
WebMay 14, 2024 · $$\tan\left(\frac{\pi}{2} -\theta \right) = \cot \theta$$ I can prove this by changing into $\cos$ and $\sin$ But I want to know if it is possible to prove it using relation given below. If not ... WebJun 21, 2016 · We first rewrite $$ \cos(\pi/2 - \pi \cos \theta) = \cos(\pi \sin \theta) $$ (cofunction identity). We notice that $\cos(x)$ is a periodic function with period $2\pi$, so we need a period offset term to be sure that we find all solutions.
