Similar right triangles showing sine and cosine of angle Neither sine nor cosine can ever exceed 1 and the closer one of them is to 1 the closer the other must be to 0 We can see this in two ways It follows Let theta in mathbb R note that cos 2 theta 1 sin 2 theta Then by assumption cos 2 theta 1 4 cos 2 theta so cos 2 theta 1 5 Share
Given that sin 2cos 1 then prove that 2sin cos 2 Solution Given sin 2cos 1 We have to prove that 2sin cos 2 Squaring on both sides sin 2cos 1 By using How do you simplify cos 2 theta 2 sin 2 theta 2 How do you find the exact value of cos2x using the double angle formula given cosx 2 13 pi 2
