Example 7 (ii) Find Integral ∫ sin 2x cos 3x dx Teachoo
Explanation: Use integration by parts, which takes the form: ∫udv = uv − ∫vdu. For ∫udv = ∫x2sin(x)dx, we let: u = x2 ⇒ du dx = 2x ⇒ du = 2xdx. dv = sin(x)dx ⇒ ∫dv = ∫sin(x)dx ⇒ v = − cos(x) Thus, substituting these into the integration by parts formula, we see that: ∫x2sin(x)dx = −x2cos(x) − ∫( − 2xcos(x))dx.

Method 1: Integral of Sin^2x Using Double Angle Formula of Cos. To find the integral of sin 2 x, we use the double angle formula of cos. One of the cos 2x formulas is cos 2x = 1 - 2 sin 2 x. By solving this for sin 2 x, we get sin 2 x = (1 - cos 2x) / 2. We use this to find ∫ sin 2 x dx. Then we get.

30. First we split sin2(x) = (1−e2ix)+(1−e−2ix) 4 sin 2 ( x) = ( 1 − e 2 i x) + ( 1 − e − 2 i x) 4. To avoid the pole at x = 0 x = 0, drop the path of integration a bit below the real line (this function has no poles and it vanishes at infinity, so this is okay). Next, let γ+ γ + be the path below the real axis, then circling back.
