Identities. tan x = sin x/cos x: equation 1: cot x = cos x/sin x: equation 2: sec x = 1/cos x: equation 3: csc x = 1/sin x: equation 4 Cos2x = cos²x - sin²x Hence 1 + Cos2x = 1 + cos²x - sin²x 1 + Cos2x = cos²x + cos²x 1 + Cos2x = 2cos²x 2019-12-27 2015-04-22 1st Pythagorean Identity $$\sin^2(x) + \cos^2(x) = 1$$ Proving the 1st Pythagorean Identity. First, we start with a right-angle triangle. This triangle will have one side along the x-axis, another parallel to the y-axis, and the third as a radius of a circle centered at the origin. Cos 2x is also called a Double angle formula as they have 2 or double angles in the trigonometric functions. Practice Cos 2x formula examples and other trigonometric formulas at BYJU'S.
