Topic: Trying to graph a conic section...
Hello,
I'm trying to find the foci of the following conic section in general form as follows:
0.27067 x^2 + 2.4674 y^2 + 1.63445 xy + 364.02 x -359.4526 y - 25987.84 = 0
To input the function f(x) it complains about y?
How do I do this please?
Thanks in advance

Re: Trying to graph a conic section...
To plot an implicit function you need to use Function|Insert relation. You also need to change xy to x*y, so the equation becomes:
0.27067x^2 + 2.4674y^2 + 1.63445x*y + 364.02x -359.4526y - 25987.84 = 0
You probably need to zoom out to see the plot.
