I shall plot the contour diagram of(adsbygoogle = window.adsbygoogle || []).push({});

[tex] z = (x^2 - y^2) * e^ {-x^2 - y^2} [/tex]

for z = O this is easy, however, if z = 1 one gets

[tex] ln (x^2-y^2) = x^2 + y^2 [/tex]

Does anyone know how to draw this?

I tried to find the intersection between two functions y1 and y2 being the lhs and rhs of the above equation respectively; but since I don't know how to draw y = ln (x^2 - y^2) either I have no clue how this is supposed to work.
