Implicit Differentiation:

Differentiate both sides with respect to , keeping in mind the chain rule when
differentiating an expression involving (since is itself a function of ).

Applications of the Derivative
Related Rates:
1.
Draw a diagram representing the situation.
2.
Identify the two quantities of interest (e.g. r = radius, A = area). In most cases, the rate
of one variable will be given, and the rate of the other variable is being asked for.
3.
Identify all information given about quantities in the problem (e.g.
4.
Determine the relation between the quantities (e.g.
5.
Differentiate the relation with respect to time and algebraically solve for the unknown
derivative (e.g.
).
6.
Substitute the known values of each variable to find the numerical value of the
unknown rate. Sometimes the quantity of only one variable is given while both are
needed. To find the value of the other quantity use the relation between the two
quantities, substitute the known quantity and solve for the unknown.

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.
Optimization Problems:
1.
Determine all quantities of interest (e.g. h = height, w = width, A = area)
2.
Determine the relationships between quantities (e.g.
3.
Identify the objective function (e.g.
4.
Use the relationships to write the objective function in terms of only one
variable (e.g.
, therefore
).
5.
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.
