Question

all the equation for teacher cos square theta upon cos square theta minus cos square theta​

Answer 1

Answer:

tan(theta) = sin(theta) / cos(theta) = a / b. cot( theta) = 1/ ... 2 sin x cos x. cos(2x) = cos^2(x) - sin^2(x) = 2 cos^2(x) - 1 = 1 - 2 sin^2(x).

Answer 2

$\bf\large\underline\red{Solution:-}$

➤ Cos2Q /Cos2Q - Cos2Q

➤ 1 - Cos2Q

➤ Sin2Q
