The cubic equation for dy/dx=0 was:
Discrete and discreet are not the same.
The same one as what?
I get it. You are worried about my kidney stone but are trying to be discreet about it. Too late! I've told everyone now.
That is the same one.
What is this topic?
The other what?
Antonym reply done.
What's even more interesting is that it seems there are more than one values of k which do that. If I remember correctly, something similar should happen at +/- 2sqrt(33).
Oh, you are right. I will try getting the exact answer if possible.
But k is any real number so you must have checked an infinite number of cases. I'm impressed.
Well, I have checked all k between -10 000 and 10 000 and in no case was there 2 stationary points.
