The plotting (sketching) of curves defined in polar coordinate system on the plane is studied. Examples of plotting curves defined in polar coordinate system are given. The variants of the tasks for independent work are presented. The material is available to high school students and can be suggested for their acquaintance with the polar coordinate system, as well as for working with students of the first semester.

The article analyses graphing (sketching) of curves given parametrically without full study using derivatives. The graphing is made with the help of auxiliary curves. This approach to graphing allows to use the article in work both with schoolchildren and with first-year students. The authors give examples of curves graphing and variants of tasks for independent work.
