Question

Hi, can someone please tell me how to integrate (x)(e^-x^2)

Answer 1

int by u-sub
let u = -x^2

Answer 2

so I just tried it would i get something like this: -du/2 = dx?

Answer 3

u = -x^2
du = -2x dx
-du/2 = x dx

Answer 4

oh whoops i forgot the x
and once I integrate, would I get the following : (e^u)(x) and get (e^u)(x^2/2)

Answer 5

is there any product rule involved since e^u is being multiplied by x?

Answer 6

see your integral shoul becomes
