To Convert from Cartesian to Polar. When we know a point in Cartesian Coordinates (xy) and we want it in Polar Coordinates (r) we solve a right triangle with two known sides. Example What is (125) in Polar CoordinatesA polar curve is symmetric about the x-axis if replacing by in its equation produces an equivavectort equation symmetric about the y-axis if replacing by in its equation produces an equivavectort equation and symmetric about the origin if replacing by in its equation produces an equivavectort equation.. In Cartesian coordinates the radius vector isIn this section we will introduce polar coordinates an alternative coordinate system to the normal CartesianRectangular coordinate system. We will derive formulas to convert between polar and Cartesian coordinate systems. We will also look at many of the standard polar graphs as well as circles and some equations of lines in terms of polar coordinates.

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 (vectorogous to the origin of a Cartesian coordinate system) is called the pole and the ray from the pole in the reference direction is the polar Polar coordinates with polar axes. The red point in the inset polar (rtheta) axes represent the polar coordinates of the blue point on the main Cartesian (xy) axes.Section 3-8 Area with Polar Coordinates. In this section we are going to look at areas enclosed by polar curves. Note as well that we said enclosed by instead of under as we typically have in these problems.

NOTE This page uses common physics notation for spherical coordinates in which is the angle between the z axis and the radius vector connecting the origin to the point in question while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use and so care must be taken in Spherical Coordinates. Spherical coordinates also called spherical polar coordinates (Walton 1967 Arfken 1985) are a system of curvilinear coordinates that are natural for describing positions on a sphere or spheroid.Define to be the azivectorl angle in the -plane from the x-axis with (denoted when referred to as the longitude) to be the polar Home.
