The equation is this
B = e ^(xy/2)
I have successfully found all 6 first and second order partial derivatives but need help finding the CP [/FONT]
I assume you mean critical point? If that's what you're talking about, then is a critical if is in the domain of and:
1)
OR
2) one or both of and are undefined.
In the case of :
Knowing this, must be a critical point because when . Similarly, when . Since can never equal , the only critical point is .
