Question

can someone help me integrate this? preferable with integration by parts

0.5xe^(0.5x^2)

Answer 1

I think it's probably better to use a substitution instead, should be much easier that way. Try \(u=.5x^2\) that should work.

Answer 2

\[\int\limits_{?}^{?}0.5^{?}\times \epsilon ^{0,5}\]

Answer 4

yup. it should be using substitution method

Answer 5

It won't work by parts at all...

Answer 6

it works fine by parts since a polynomial derives to 0

Answer 7

u = .5 dv = x e^(.5x^2) dx
du = 0 dx v = e^(.5 x^2)


int [u dv] = uv - int [v du]

int [ .5* xe^(.5x^2)] dx = .5*e^(.5 x^2) - 0 int [e^(.5 x^2)] dx
=0

int [ .5* xe^(.5x^2)] dx = .5*e^(.5 x^2)
