Write integrand as sin x cos x 2 frac 1 2 sin 2x 2 Then use the following facts sin 2 2x 1 cos 2 2x cos 2 2x frac 1 2 cos 4x 1 Note The original question Free Integral Calculator helps you solve definite and indefinite integration problems Also double triple and improper integrals Answers graphs alternate forms
To integrate sin 2x cos 2x also written as cos 2 x sin 2 x dx sin squared x cos squared x sin 2 x cos 2 x and sin x 2 cos x 2 we start by using standard trig identities to to change the form The integral of sin 2x dx is cos 2x 2 C whereas the integration of sin 2x dx is x 2 sin 2x 4 C Learn these formulas along with their proofs using the substitution method
