    Here's the neater version (avoid the f(x) and g(x)'s when solving problems) of the integration by parts rule:

    [tex]
    \int u dv = uv - \int v du
    [/tex]

    Now follow Parth Dave's advice. I mentioned this as some old books still use f(x) and g(x) instead of the neater looking u and v. (Oh well, you might use f and g instead of u and v ;-))

    Cheers
    Vivek
