Abstract
Abstract This paper discusses how to graph a polar function r=f(\ensuremathθ). Graphing a polar function is accomplished in pretty much the same manner as a rectangular function is graphed. They can be graphed by point-plotting, using the trigonometric functions period, and using the function?s symmetry (if any). When graphing rectangular function by point-plotting we would pick values for x and then evaluate the function to determine its corresponding y-value. For a polar function, we would pick angle measurements for \ensuremathθ and then evaluate the function to determine its corresponding r-value. In Microsoft Office Excel worksheet, a point (f(\ensuremathθ),\ensuremathθ) will be plot in scatter chart as (f(\ensuremathθ)cos(\ensuremathθ),f(\ensuremathθ)sin(\ensuremathθ) ). Keywords: polar function, Microsoft Office Excel
