Mathematica Complex Numbers Polar Form

Let r θ be a polar representation of the point with rectangular coordinates a b where r 0. I took the modulus of the complex number in question to get r and in order to obtain theta i used the unit circle. You can express a complex number z in polar form r cos theta i sin theta where r abs z and theta arg z.

The set of all arguments of z is denoted arg z.

Mathematica complex numbers polar form. Endgroup user606466 jan 26 19 at 13 36 begingroup while we prefer fractions to be written frac nd in most places that format doesn t work well in an exponent. However this creates a discontinuity as moves across the negative real axis. Finding the absolute value of a complex number. The modulus of z denoted z is defined by z r.

Polar form of complex numbers plotting complex numbers in the complex plane. Representations of complex numbers. As numeric objects in radians quantity objects with any angular unit or degree minute second dms lists and strings. Angles and polar coordinates representing complex numbers vectors or positions using angles is a fundamental construction in calculus and geometry and many applied areas like geodesy.

Convert a complex number to the ordered pair. The first step toward working with a complex number in polar form is to. Let z a bi be a complex number with a re z and b im z. Plotting a complex number a bi is similar to plotting a real number.

Ken levasseur umass lowell march 2011. The new functions reim and absarg make it easy to convert a complex number to either its cartesian or polar representation. All applicable mathematical functions support arbitrary precision evaluation for complex values of all parameters and symbolic operations automatically treat complex variables with full generality. The wolfram language offers a flexible variety of ways of working with angles.

Every complex number written in rectangular form has a unique polar form up to an integer multiple of in its argument. The wolfram language has fundamental support for both explicit complex numbers and symbolic complex variables. Get the free convert complex numbers to polar form widget for your website blog wordpress blogger or igoogle. The principal value of the argument is normally taken to be in the interval.

Reim 3 4 i out 1. Find more mathematics widgets in wolfram alpha. So the only mathematica commands you need are abs and arg. The angle θ is an argument of z.
