What does the second derivative measure?
A stationary point with f′′(x)>0f''(x)>0f′′(x)>0 is a local minimum.
The test is inconclusive; inspect the first derivative on either side.
At a stationary point, f′′(x)>0f''(x)>0f′′(x)>0 indicates a local minimum.
Rate of change of the gradient with respect to xxx.
