Parametric Equations

Hello,

This week we learned about parametric equations. This is the first part of our calculus integration, and is a very simple topic. Parametric functions set parameters, and tell us the direction, start and end points. In solving, we are given two values, x and y. These are generally either given in trigonometric functions such as: sin(x), cos(x), tan(x), etc... There are other variations and transformations of these basic functions. When solving parametric equations, we do so by eliminating the parameter. By solving for t, we can substitute into the y= equation and eliminate the parameter. To graph them, we make a chart and plug in values in the range for "t". We can graph the xy points created by the table, and successfully graph the Parametric function.

Thanks,
