1. The problem statement, all variables and given/known data

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

$0\leq\lambda x\leq2\Pi$ and $0\leq\omega t\leq2\Pi$

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 $10e^{-\lambda x}$ between 10 an $10e^{-2\Pi}$
