Can Grapher evaluate a function?
I just noticed that Grapher fails to evaluate a function at a constant. In the image, the graph of y = c should of course be a horizontal line. Is there a way to fix or work around it? This seems like such a fundamental bug that I can't understand why I haven't run into it before.
Well, the problem is that Grapher assuming that the x in f(x)=x^2 means the x coordinate.
To fix this problem, you should change the x to some other variable (say z).
I know, Grapher is weird sometimes.
