Can anyone help me graph the contour curve for the function:
f(x,y)=2x^2+2xy-2y^2
and determine the two straight lines of the contour curve f(x,y)=0 across the origin.
Thanks in advance.
It is my homework but I have no software to plot the curve.
Thanks again.

✔ 最佳答案
This website can plot it for you:http://www.wolframalpha.com/
Input: "plot z=2x^2+2xy-2y^2" and press "=".
Then you will get the contour curve.
