Converting Cartesian graphs into polar graphs
- Mr Hardman
How do sine and cosine functions look in polar form?
Use the sliders on the left and button on the bottom to change your function, r = a + bsin(nx) or r = a + bcos(nx). From the Cartesian/rectangular graph on the left, see how the polar graph is plotted as you move along it (use the slider). Press Show negative r to see where negative r values are plotted once you have plotted the polar graph.
