These programs visualize and solve high-level mathematical equations, conveniently graphing them for you on an EGA monitor. Great for students, scientists, or anyone who just enjoys math. The DIFFERENTIAL EQUATION program can solve a variety of both ordinary and partial differential equations. You can also integrate factors of an equation, and create a graph of power selies solutions. Use the CALCULUS program to find the derivatives of an expression in x and/or y. Other features include graphing functions of y=f(x), graphing first and second derivatives, solving and graphing parametric equations, finding the integral of simple functions, and finding the surface contour of a function z=f(x,y). An MS-Windows version is available for registered users. Minimum Requirements: EGA or VGA.
