Now, if I draw the following:
With Wolfram I get the following graph.
But if I draw the following functions that I have solved for Y
I seem to be loosing some information
Is all this simply a consequence of the following math:
Squaring could cause this, but is that what I have done here? The reason for my post is that when doing the calculations by hand I still find the two intersections. But it is not visible in the graphs of the very same functions that on paper gives me what I want.
