To find local maxima and minima of a function, use the second derivative test and set the first order partial derivatives equal to 0.
A system of simultaneous equations can help simplify the problem.
The second derivative test is used to find local maxima and local minima of a multivariable function.
To use the second derivative test to find local maxima and local minima of a multivariable function, you need to find the critical points of the function and determine whether the second order partial derivative with respect to x is positive or negative at each critical point.
