Differentila Equation

ALL-IN-ONE MULTI-PHYSICS FINITE ELEMENT MODELING Ever wish there was a flexible system for solving all the partial differential equation problems that come up in science and engineering, so you didn't have to buy and learn a new software tool for each problem? Well, now your wish has come...

Need a tad of help with an equation? Do you think you could use an application which offers easy access to formulas and to a unit converter? Then Microsoft might have the right answer for you. Microsoft Mathematics 4.0 is now available as a free download from the Redmond company. The tool...

This game challenges your reaction speed and judgement. You will be presented with a simple equation and you need to fill in the missing mathematical symbol to complete as quickly as possible. The faster you answer, the higher your score.

This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD).The base input PSD must be in terms of acceleration.The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles...
