Plotting polar equations requires the use of polar coordinates, in which points have the form , where r measures the radial distance from the pole o to a point p and measures the. In this video i go over how to graph polar equations using geogebra. The best way to sketch the polar curve is to set that argument inside the trig function equal to pi/2, and then solve that equation for theta.
Finding the diameter and radius of circle from the equations r = cos theta and r. To display a curve defined by a polar equation in a cartesian grid, that is usually the case, instead of using the polar library, set data. Restrict the graph for r >= 0.
