In this video we are going to solve step by step 3 examples about RELATED CHARGES.
To resolve fee-related issues, we must follow a script:
1 - Build a DIAGRAM, if possible.
2 - Identify the VARIABLES involved in the problem.
3 - Find an EQUATION involving the variables of the problem. If necessary, use situation geometry to eliminate one of the variables by substitution.
4 - After simplifying the found equation, DERIVE both sides of the equation with respect to t using the CHAIN RULE.
5 - Only after deriving both sides of the equation should you substitute the value of each variable in the resulting equation to determine the unknown rate.
