Homework Statement
Find the path ##\vec\gamma(t)## which represents the level curve ##f(x,y) = \displaystyle\frac{xy + 1}{x^2 + y^2}## corresponding to ##c=1##.
Similarly, find the path for the curve ##x^{2/3} + y^{2/3} = 1##
Homework Equations
None.
The Attempt at a Solution
Since the level set corresponds to ##c=1##, ##xy + 1 = x^2 + y^2##.
At this point, I know that ##x^2 + y^2 - xy = 1## is an ellipse, but I cannot put it into a form that is similar to how the path for the general ellipse ##\displaystyle\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1## is ##\vec\gamma(t) = (acos(t), bsin(t))## because of the ##xy## term.
Same thing for ##x^{2/3} + y^{2/3} = 1##. It almost looks like the general form, but not quite. Any suggestions?
