Applications of the Derivative
Critical Points: There are three types of critical points...
1.
Stationary points are the values of x where
(e.g. numerator is 0).
2.
Singular points are values of x where
3.
End points are the boundary points of the domain on which
(e.g. on the interval
the end points are
and
)
is undefined (e.g. denominator is 0).
is being considered.
Extreme Values: Maximum and Minimum values of a function
1.
The extreme values of a function MUST occur at a critical point
2.
To find the extreme values of a function first find the critical points, then evaluate
the function at all known critical points to determine which is the maximum value
and which is the minimum value.

Determine the maximum/minimum value of the objective function by first
finding all critical points and then plugging the critical points into the objective
function to determine which yields the optimal value. In some problems you are
looking for the maximum value and in others you will be looking for the
minimum value.
Newton’s Method
To solve
, start with an initial guess, . Then take successive guesses
according to the following recursive formula until your approximation is reasonably
close to the true solution:
