Interactive Cartesian Coordinates. Drag the points on the graph, and see what is going on. Can be used to draw shapes using cartesian coordinates (use Edit to add more points). Cartesian Coordinates Hit the Coordinate Game Polar and Cartesian
Vector and Matrix Data. polarplot (theta,rho) plots a line in polar coordinates, with theta indicating the angle in radians and rho indicating the radius value for each point. The inputs must be vectors of equal length or matrices of equal size. If the inputs are matrices, then polarplot plots columns of rho versus columns of theta .
Plotting Points Using Polar Coordinates So far, we’ve plotted points using rectangular (or Cartesian) coordinates, since the points since we are going back and forth units, and up and down units. In the Polar Coordinate System, we go around the origin or the pole a certain distance out, and a certain angle from the positive – axis:
Polar Numeric Solutions Solve for zeros of any curve Find intersections of curves Identify minima and maxima Evaluate numeric expressions Animation Very easy to animate objects Use sliders to explore curve families Easily creates movies Other Features Drag terms with the mouse to transform expressions Create web pages Define variables
In case you haven’t been paying attention in class, polar graphs are like your typical Graph Paper Template and are used the same way: to create graphic projections of certain data. In the case of polar graphs, they help you plot out polar coordinates. Usually, you will be utilizing them to measure radius as a function of angle.
