Websin 2 x + cos 2 x = 1 is basically just the Pythagorean identity ( a 2 + b 2 = c 2) expressed in Trigonometric terms instead of Algebraic terms. And that's important because the Pythagorean theorem is the basis for almost all trigonometry. – RBarryYoung Mar 21, 2014 at 16:57 Add a comment 2 Answers Sorted by: 11 Webcos3x = cos (x+2x) It can also be written in this form. = cosxcos2x−sinxsin2x {as per the identity: Cos (x+x) = Cos (x) Cos (x) − Sin (x) Sin (x)}…Eq1. = Now as we know, Cos2x = 2Cos ²x – 1; Sin2x = 2SinxCosx.

WebSep 15, 2024 · We know the double angle formula for sine is sin ( 2 x) = 2 sin ( x) cos ( x). For convenience, let x = 2 θ. Then 4 θ can be written as. 4 θ = 2 ( 2 θ) = 2 x. 1 2 sin ( 4 θ) = 1 2 sin ( 2 x) = 1 2 ⋅ 2 sin ( x) cos ( x) = sin ( x) cos ( x). But wait--we said x = 2 θ !
