I have
x,y = var('x y')
f = (2x + 3y == 0)
How do I plot it
plot(f) gives the error:
Traceback (click to the left of this block for traceback) ... ValueError: Variable 'y' not found
And since it complained about y, why didn't it complain about x? Also, where would I find the docs for this question?
And yes, I am a beginner at sage
