Message-ID: Keywords: HP Nntp-Posting-Host: aix01srv.aix.rpi.edu Organization: Rensselaer Polytechnic Institute, Troy NY Date: 5 Apr 91 03:10:15 GMT Lines: 17 Hi, I was wondering if there's an easy way to enter in two or more equations and have the HP solve for them simultaneously. These equations are not the simple 3x + 4y.....= 3 type equations. They're more like 1 -T/rt --- = c e x (Arrehnious)..and I don't really know how to stick that into a matrix. Is there a way to just type in 2 equations with two unknowns in the eqn writer (or directly) and press a solve key and it'll solve for the two unknowns? I know Eureka, by Borland, for the IBM can do this. -- | Internet: Eric_Hsiao@MTS.RPI.EDU > Read GIF News - a freely copied news < | | sunyat@rpi.edu > magazine in .GIF file format.
