EXAMPLE: \frac{dc}{dv} = \frac{160}{v} + \frac{v^2}{100}

                   \frac{dc}{dv} = -160 v^{-2} + \frac{2v}{100}

                   -160 v^{-2} + \frac{2v}{100} = 0

                                

Step 3: Solve the equation to find the unknown value.


            EXAMPLE:   -160 v^{-2} + \frac{2v}{100} = 0

                               \frac{-160 * 100}{v^2} + 2v = 0

                               -160 * 100 + 2v^3 = 0

                               2v^3 = 16000

                               v^3 = 8000

                                          v = 20
