Hey guys, I tried it out, but I just don't get it. I have to find the equation for the level curve f(x, y)=(x^2 + y^2)e^(xy); that contains the point P(1,0). By the way, e^(xy) is read e to the x times y, just in case.(adsbygoogle = window.adsbygoogle || []).push({});

What I did, which looks wrong the whole way was:

(x^2 + y^2)e^(xy) ---> (x^2)(e^(xy)) + (y^2)(e^(xy)) = 0

---> ln(x^2) + ln(e^(xy)) = (-1) ln(y^2) + ln(e^(xy))

---> 2ln(x) + xy = (-1) (2ln(y) + xy)

---> 2ln(x) = (-1)(2ln(y))

...and i'm stuck there. Could anyone help correct this, or if possible, help continue? Thanks a bunch.
