Comment by Perez-Franco: I am an asiduous user of this program. I consider it the most advanced math program ever created for any calculator. This small program can solve advanced math problems that could give even an advanced math programs on a PC a nice headache. And it works fast and accurately! This program is required by the latest versions of Symbulator, but even if you don't use Symbulator, I recommend you to get this program: it is a must! |

Description by the author (Lars Frederiksen): This package is
primary designed to solve high order differential equations. There are two functions for
those purposes: a single and a simultaneous equation solver. The single equation solver
will solve a long range of different types of equations. As a speciality it has the
ability to solve literary all Linear (non) homogeneous and Euler equations up to an order
of 9. The simultaneous solver will solve systems of two or more Linear equations of any
order using Laplace transformation. The package does also include functions for basic
Laplace / inverse transformation (these functions does not support Delta/Heaviside
function or more advanced transforms). It includes an archiver
application.
Description: This package contains functions for solving
single or multiple differential equations with constant coefficients. Differential
equations can be of any order and complexity. The functions have also the ability to find
the solutions of most integral equations or combinations of differential and integral
equations (integro-differential equations). Method used: Laplace-transformation. This
package does also contain functions for Laplace-transformation. The difference from
the program above is that Advanced Laplace has more advanced Laplace capabilities.
Description: This packet contains functions to perform
Fourier-/inverse Fourier-transformation. A function, which can rewrite the output of
Fourier/iFourier to a form that, can be evaluated numerical. A function to graph the
output. It will now do cyclic (v(t) <-> V(f)) as well as angular (f(t) <->
F(w)) frequency transformations. It will now do cyclic (v(t) <-> V(f)) as well as
angular (f(t) <-> F(w)) frequency transformations.
