    Let [tex]u=e^y[/tex]

    Now it should be a lot easier.

    Note that, with homework questions, we require that you show your work before we help you, as per PF rules.

    Why do (almost) everyone assume that my posts are homeworks questions? Is it invalid to post some (sensible) problems that one made up him/herself to learn the ways others solve it? LOL :tongue:

    Possibly because you keep posting them in the Homework and Coursework section?

    Actually he posted them in the Calculus & Analysis forum, and they got moved here. But more importantly, even if they are not homework questions, PF members are under no obligation to solve them for you. The same rules apply here as well.

    So it's not a homework problem. It's just a problem you want other people to solve for you. Thats much better.:rolleyes:

    Regardless, the forum rules state:
    Furthermore, if you read the forum rules, you must show us some work before we can help you.
