If cos θ + sin θ = √2 cos θ, prove that cos θ sin θ = √2 sin θ. This definition means that when going a distance of $\theta$ counter-clockwise along the unit circle starting at $(1,0)$, the coordinates of the point on the circle are $(\cos \theta, \sin \theta)$. Verified answer. Find the adjacent side of the unit circle triangle. Therefore, the expression is proven
