NettetThe integral of the first one is easy, it's just − 1 a exp ( − a x), as said in the posts. The limit of a negative exponential to ∞ is just 0 and to 0 is 1. So we get: − A d d a ( 0 − 1 a) = − A a 2. With this method you can integrate. ∫ 0 ∞ A x n exp ( − a x) for every n ∈ N. Share.

How do you integrate int xe^(-4x) by integration by parts method ...
Nettet9. jun. 2015 · This seems to be: int xe^(3x)dx e^3(x) wouldn't make sense (e is a constant, not a function), and e^3x ne (ex)^3 (improper implications from trig^n(x) = (trigx)^n). e^(x^3) would be very advanced to integrate, and would not be remotely easy by integration by parts. x^2e^3 would be way too simple. Nettet0, + ∞ range. In this case, starting from the integration by part, you will get an easier result: ∫ + ∞ 0 xe − x ( 1 + k) dx = 1 (1 + k)2. Hence the series would be. + ∞ ∑ k = 0 1 (1 + k)2 = + ∞ ∑ k = 1 1 k2 = ζ(2) = π2 6. Indeed that series would be nothing than the Riemann Zeta Function evaluated at the point 2. Share.
