Answer to Question #214759 in Calculus for Maryam

Question

Explain when it is necessary to convert a double integral from cartesian coordinates to

polar coordinates.

Answer 1

The cartesian cordinates is useful in situations where the domain can be expressed simply in terms of x and y. However, many problems are not so easy to graph. If the domain has the characteristics of a circle or cardioid, then it is much easier to solve the integral using polar coordinates
