rectangular_coordinates and polar_coordiantes - Eddie W. Shore - 02-06-2014 08:55 PM It turns out that the HP Prime does have rectangular-polar conversion functions. They are buried in the catalog. Syntax: rectangular_coordinates(r, θ) or rectangular_coordinates([r, θ]) returns the vector [x, y] Example: (Radians mode - CAS mode, works in Home mode too) rectangular_coordinates(3, π/3) returns [3/2, 3*√(3)/2] (≈ [1.5, 2.59807621135] ) polar_coordinates(x,y) or polar_coordinates([x,y]) returns the vector [r, θ] Example: polar_coordinates(3,4) returns [5, ATAN(4/3)] (≈ [5, .927295218002] ) RE: rectangular_coordinates and polar_coordiantes - josephec - 02-07-2014 02:48 AM Hi Eddie, Even much more easy, with version 5447 (2013 11 25), Enter your rectangular like 7+9*i then press [SHIFT] then [x] //where the angle symbol <) is, and will show 11.40...<)52.12... // in degrees or 11.40...<).90... // in radians It help me much and I hope to You too. best regards!! joseph |
