The analytical method is an approach used in calculus for solving optimization problems algebraically using derivatives and critical points. It involves finding these critical points by taking derivatives and analyzing their behavior.
A method used to determine whether a critical point is a maximum, minimum, or neither by evaluating the sign changes of the derivative.
Another method used to determine if a critical point is a maximum, minimum, or neither by analyzing the concavity of the function.
Closed Interval Method: This approach involves checking both endpoints and critical points within a closed interval to find absolute maxima or minima.
