#1201: Integration by Parts
A guide to integration by parts:
Given a problem of the form:
â«f(x)g(x)dx = ?
Choose variables u and v such that:
u = f(x)
dv = g(x)dx
Now the original expression becomes:
â«udv = ?
Which
definitely
looks easier.
Anyway, I gotta run.
But good luck!
{{Title text: If you can manage to choose u and v such that u = v = x, then the answer is just (1
2)x^2, which is easy to remember. Oh, and add a ‘+C’ or you’ll get yelled at.}}
