You can do an integration by parts :
, which is something like
You should know an antiderivative for it
And then, iterate the integration by parts 3 times (I think)
Hello people; here's how it goes, i'm writing my masters dissertation at the moment about the mechanical properties of metallic glasses (interesting stuff eh?!!) and i've got to integrate a function. Now, i got 34% on my undergrad calc test so, try as i might, i just can't do it! Please can someone throw me a lifeline!!
Here's the function to integrate y = (x^4.e^x)/((e^x-1)^2) dx
