The spreadsheet can be used to display the graph of parametric equations. One way is to place an initial value of the parameter t in cell A1 and increment t in the A column. Then if we put the formula for the x-coordinate, in B1 and the y-coordinate in C1, we can fill down to get the appropriate range of t and then graph. Below are some graphs of parametric equations using problems from assignment 10.

Lets start with the following equation.
