Question
Use integration by parts to prove the reduction formula.$\int x^n e^x d x=x^n e^x-n \int x^{n-1} e^x d x$
Step 1
If u and v are functions of x, then: $$\int u(x) \cdot v'(x) \, dx = u(x) \cdot v(x) - \int v(x) \cdot u'(x) \, dx$$ Show more…

Integration by Parts
Use integration by parts to establish the reduction formula. $$\int x^{n} e^{a x} d x=\frac{x^{n} e^{a x}}{a}-\frac{n}{a} \int x^{n-1} e^{a x} d x, a \neq 0$$
Use integration by parts to prove the reduction formula. $\int(\ln x)^{n} d x=x(\ln x)^{n}-n \int(\ln x)^{n-1} d x$
