unknown quantities (if there are any of course) to this variable.
4. If applicable, sketch a figure illustrating the situation. This may seem like a silly step,
but it can be incredibly helpful with the next step on occasion.
5. Form an equation that will relate known quantities to the unknown quantities. To do this
make use of known formulas and often the figure sketched in the previous step can be
used to determine the equation.
6. Solve the equation formed in the previous step and write down the answer to all the
questions. It is important to answer all the questions that you were asked. Often you will
