WebOct 27, 2024 · The derivative of cos 2x with respect to the variable 'x' is equal to -2sin 2x. It is denoted by d / dx (cos (2x)). It is the rate of change of the trigonometric function cos s. In a triangle, it is the ratio of adjacent to hypotenuse. It is written as; c o s x = B a s e H y p o t e n u s e Derivative of cos 2x formula WebSin^2x Formula in Terms of Cosx We have the Pythagorean trigonometric identity given by sin^2x + cos^2x = 1. Using this formula and subtracting cos^2x from both sides of this identity, we can write it as sin^2x + cos^2x -cos^2x = 1 - cos^2x which implies sin^2x = 1 - …
