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 analogous 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 axis.
Coordinate systems provide a way to define a point in space in either one, two, or three dimensions. The most prevalent coordinate system used in linear motion applications is the Cartesian system. Cartesian coordinates define a position as the linear distance from the origin in two or three mutually perpendicular axes. The origin is the point where the axes intersect, and points along the axes are specified by a pair x, y or triplet x, y, z of numbers.

However, as we will see, this is not always the easiest coordinate system to work in. So, in this section we will start looking at the polar coordinate system. Coordinate systems are really nothing more than a way to define a point in space. This is shown in the sketch below. This is not, however, the only way to define a point in two dimensional space. This leads to an important difference between Cartesian coordinates and polar coordinates. In Cartesian coordinates there is exactly one set of coordinates for any given point.
Polar and Cartesian Coordinates
Cartesian coordinates and polar coordinates, as shown below. The azimuthal coordinate is called the argument of the complex number, which is also denoted by arg z. Addition of complex number and their properties Subtraction of complex numbers multiplication of two complex no. The complex plane is known as Argand-Gauss plane. This plane as the real part of the chosen complex number as first coordinate, and the imaginary part as the second one. From this graphical representation it is easily derived the polar form of a complex number. Topics cover converting polar to rectangular; plotting polar coordinates; complex number system, and more; Also, imaginary numbers quiz, and 3 comics.

Spherical coordinates can be a little challenging to understand at first. The following graphics and interactive applets may help you understand spherical coordinates better. On this page, we derive the relationship between spherical and Cartesian coordinates, show an applet that allows you to explore the influence of each spherical coordinate, and illustrate simple spherical coordinate surfaces.

In mathematics , a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane. It can be seen as the three-dimensional version of the polar coordinate system. The radial distance is also called the radius or radial coordinate. The polar angle may be called colatitude , zenith angle , normal angle , or inclination angle. The use of symbols and the order of the coordinates differs among sources and disciplines.
Using Cartesian Coordinates we mark a point by how far along and how far up it is:. It is the Inverse Tangent Function :. Note: Calculators may give the wrong value of tan -1 when x or y are negative Answer: the point 13, When converting from Polar to Cartesian coordinates it all works out nicely:. Hide Ads About Ads.

I am confused about converting a Probability Density Function from Polar coordinates to Cartesian coordinates. But somebody told me that in this transformation, I should multiply by the absolute value of the Jacobian determinate in order to have:.
