------------------------------ Complex 1.0 by Grahame Bowland - release 08/05/98 ------------------------------ ----------- Description ----------- "Complex Numbers" is a TI-83 Program to convert complex numbers between rectanglular form, a + bi, to polar form, R[cos(theta) + isin(theta)] - also written as [r cis(theta)]. ------------- How to use it ------------- _______________________________________________________ 1: Rectangular form, a + bi, to Polar form, r cis(theta) Enter a and b as prompted. For example, to convert the equation y = 3 + 4i enter: 3 4 The equation is then converted to polar form, with theta (RADIANS) in the correct quadrant of the unit circle. _________________________________________________________ 2: Polar form, r cis(theta), to Rectangular form, a + bi Enter r and theta as prompted. Note that theta must be entered in RADIANS or enter the angle in degrees followed by a degree symbol - found on the Angle Menu. For example, to convert the equation y = 5 cis(60°), enter: 5 60 <2nd><1> To convert the equation y = 5 cis (pi / 4), enter: 5 pi / 4 The converted form of the equation is then displayed. ------ Author ------ Grahame Bowland Homepage: http://www.wantree.com.au/~bowest/gmb.html ---------------------- Copyright & Disclaimer ---------------------- Copyright 1998 Grahame Bowland This software may be freely distributed as long as the author (Grahame Bowland) is acknowledged.
