Homework Help: Orthogonal Trajectory. Calc IV.

  1. Sep 6, 2012 #1
    1. The problem statement, all variables and given/known data

    Find orthogonal trajectories for y=clnx, y=cex, y=sin(x)+cx

    2. Relevant equations

    Simple integration for the most part.

    3. The attempt at a solution

    I'm fairly confident on the first two, its the third that's giving me trouble.

    First, y=cln(x)
    [itex]\int[/itex]-xln(x)dx=[itex]\int[/itex]ydy using IBP

    Second, y=cex

    Third, y=sin(x)+cx2

    I've been unable to make any more progress.

    Can nobody give me an idea of where I should go from here? I don't know if I'm having a simple algebra problem or what.

    Why won't any one help me?! I need to know how to solve this problem before class!
