Partial fractions decomposition is the opposite Sin 2x Cos 2x value is given here along with its derivation using trigonometric double angle formulas. Also, learn about the derivative and integral of Sin 2x Cos 2x at BYJU’S. 2008-11-16 · Those right triangles therefore each have area (1/2)sin (x)cos (x) so adding the areas together gives area of the isosceles triangle as sin (x)cos (x). Equate the areas: (1/2)*sin (2x)*1 = sin (x)cos (x), multiply by 2: sin (2x) = 2sin (x)cos (x). Show more.
