Substituting in the expression above: ∫cos4xdx = sinxcos3x 4 + 3 8(cosxsinx) + 3 8 x. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β. So assume a = cos2x cos 2 x and b = sin2x sin 2 x then we get, ⇒ (cos2x)2 − (sin2x)2 = cos4x −sin4x ⇒ ( cos 2 x) 2 − ( sin 2 x) 2 = cos 4 x −
