I have this function:
f(x,y) = (x+y)^2
I would like to draw the contours by hand for c=0, c=0.5 and c=1.
for c=0 there is no contour since (x+y)^2 = 0 => x and y = 0.
Well, at least the contour is fairly small.
for c=0.5 I get:
(x+y)^2 = 0.5 => x+y = sqrt(0.5)
Wrong. There is a second possibility.
But how do I find all the values for x and y that matches that criteria?
x+y=const implies that you can write y as a simple function of x.
