From what problem did this integral arise? It doesn't seem to succumb to any standard techniques in regular calculus. You might be able to try contour integration, or maybe differentiation under the integral sign. Or maybe even Laplace Transforms.
Hi everybody
If we have not any answers for critical points after first partial derivatives equal to zero, how can we continue to find local MAX, local MIN and Saddle point?. For example: Suppose we have below equations for first partial derivatives:
∂ƒ/∂x = y + 5 , ∂ƒ/∂y = 2z , ∂ƒ/∂z = y
As you can see, for ∇ƒ= 0 , there are not any answers (undefined)
