Example. Use a double polar integral to find the volume of the solid enclosed by the given curves. z = x 2 + y 2 + 4 z=\sqrt {x^2+y^2+4} z = √ x 2 + y 2 + 4 . z = 4 z=4 z = 4 The rectangular coordinate system is best suited for graphs and regions that are naturally considered over a rectangular grid. The polar coordinate system is an alternative that offers good options for functions and domains that have more circular characteristics In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point is called the pole, and the ray from the pole in the reference direction is the polar axis. The distance from the pole is called the radial coordinate, radial distance or simply radius, and the angle is called the angular coordinate, polar angle, or azimuth.
