Plot the points of a curve whose coordinates are functions of one or more parameters.
One Parameter
1. Define the functions x and y in terms of parameter a:
2. Plot y against x. For parametric curves, 500 points are plotted over a range determined by an algorithm. When you change the number of plotted points, the range is changed accordingly.
Two Parameters
1. Set the number of data points.
2. Define the angle and the radius at each data point.
3. Define the parametrized coordinate vectors.
4. Record the above values in a matrix so that you can reuse them or write them to an external file for other applications.
5. Plot y against x. You can change the plotted points by modifying the definition of the range variable i.
6. Show the above curve as a polar plot (non-parametric).
