## Abstract

Abstract This paper discusses how to graph a polar function r=f(θ). 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 θ and then evaluate the function to determine its corresponding r-value. In Microsoft Office Excel worksheet, a point (f(θ),θ) will be plot in scatter chart as (f(θ)cos(θ),f(θ)sin(θ) ). Keywords: polar function, Microsoft Office Excel
