Homework Help: Drawing a contour map for e^(variable)sine(x-t*variable)

  1. Apr 10, 2013 #1
    1. The problem statement, all variables and given/known data

    Draw a contour map for [itex]T(x,t)=10e^{-\lambda x}\sin(\omega t-\lambda x)[/itex]

    [itex]0\leq\lambda x\leq2\Pi[/itex] and [itex]0\leq\omega t\leq2\Pi[/itex]

    2. Relevant equations

    3. The attempt at a solution

    Because those two variables are within that given range I'm not sure how to do this.

    Normally I would set f(x,y) to k and then see if a function could be drawn on the x-y plane for any given value of k. so you might get a circle of radius k. but here i'm thrown off.

    sin varies between -1 and 1 and [itex]10e^{-\lambda x}[/itex] between 10 an [itex]10e^{-2\Pi}[/itex]
