Hi, I'm selling a multimedia software CD-ROM which teaches the user about Differential Equations of college mathematics created by Pro-One Software. These equations of applied mathematics are used in the descriptions of the motions of satellites, spacecraft, planets, stars and galaxies under the influence of gravity in Celestial Mechanics. Covers nine essential elements, 30 key subject areas, over 300 practice problems and solutions, first order differential equations, applications of first order differential equations, second order differential equations, linear, constant coefficient homogenous differential equations of order three and four. The CD-ROM is playable in Windows 3.1, 9x, ME, NT, 2000 & XP. It has never been used and is still in shrink-wrap. Asking $7 + USPS media mail w/delivery confirmation.
Thanks for looking!
