If I solved an example equation like
|x|+|y|=1 numerically, I would to get a 90° rotated rectangle. If I was to plot the equation, it would result in an image like the following:
As an example, this is the problem I want to solve:
Sin[x] Sin[2y] + Sin[y] Sin[2x] = 0
May I get suggestions on the best method to plot the example problem achieving the same result?
