Step 1: Note down the given equation

Step 2: Differentiate the given equation by using the formulas

NOTE: Use the rules of the differentiation to solve the equation.

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
