Topic: normal line

Hello, I have just started using Graph so maybe it results from my poor knowledge of this program, but it seems that something is wrong in normal line formula. The tangent line is ok, but normal is not normal. Try it for simple x^2 function and at x=2.

Re: normal line

I do not see the problem. Maybe it is the scaling of the axes that is confusing you. You can try to select Zoom|Square in the menu to scale the axes equally.
