Question

Please help me find the Laplace transform of xe^x

Answer 1

do you know the formula? It is going to be a integration by parts problem

Answer 2

Yes I know that but somehow I miss the integration...

Answer 3

Im going to try to work it out

Answer 4

The result is 1/(1-p)^2
It gave me 1/(1-p) plus an integer to solve

Answer 5

did you remember to cancel terms in your substitution?

Answer 6

How so?

Answer 7

when you combine terms use u sub

Answer 8

No I didn't substitute anything.integrated by parts

Answer 9

bah, i goofed it sorry

Answer 10

\[\int\limits_{0}^{\infty}te^{t(1-s)} = t(\frac{1}{1-s}e^{t(1-s)}) - \int\limits_{0}^{\infty}\frac{1}{1-s}e^{t(1-s)}\]

Answer 11

How did yo become to this?

Answer 12

I solved the rest of the integer and didn't get the right answer that is 1/s^2
