2. Extended Keyboard. If u =x2 u = x 2, then modulo a sign, x = u−−√ x = u. Let u=x^2 and v=e^x, then du=2xdx and dv=e^xdx Now integration by parts states that intu (x)v' (x)dx=u (x)v (x)-intv (x)u' (x)dx Hence intx^2e^xdx=x^2e^x-inte^x xx 2xdx = x^2e^x
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 Simplifying the negative signs:
