The compound interest formula appears in many classes. It can be confusing to students when it appears in one class as
and in another as
These are basically the same formulas, but used in a different context. However, how you solve for the different quantities in either one is the same. The Math-FAQs below demonstrate how to solve for
Extrema are the high and low points on a function’s graph.
It can be difficult to distinguish between the bumps and dips on a graph, the relative (or local) extrema, and the very highest and lowest points on a graph, the absolute extrema.
The Math-FAQ belows show how to find each type of extrema using derivatives.
Students often struggle with calculating rates from the limit definition,
Because of this, there are many FAQs available to help you work through these problems.
These examples should help you to solve problems from Section 11.2 and Section 11.3.
Often the most difficult part of solving a system of equations problem is writing out the system from a word description. In this FAQ, we look at a complicated sounding problem and form a system of linear equations from the problem.
This FAQ explores how to take a story problem and write it out as a system of linear equations.
Excel comes in handy for creating tables of values for limits. This FAQ contains two PDFs that demonstrate the process of creating a table using a “fill” in Excel.
How Do I Make A Table Of Values In Excel?
This same process may be used to create tables in other types of spreadsheets such as Google Sheets.
