## PS Lisp

PSLisp is a Lisp interpreter Lisp for smartphones and tablets running Android.

The graphic interface allows the users to enter and evaluate Lisp S-expressions. It is possible to navigate in a ring of the evaluated expressions during a session.

S-expressions can be saved on a sdcard, and loaded in a further session.

A doc button gives access to a PSLisp manual in PDF in french and in english.

PSLisp is implemented on virtual machine written in JAVA and is also available on demand for a PC.

arithmetic but even symbolic calculations of mathematical formulas.

The current Android version 1.0 contains the following functions:

- Exact arithmetic calculations, e.g. handling of integer numbers with "arbitrary" size

- Transforming mathematical formulas, e.g. factorization of polynomials

- Discussing mathematical functions, e.g. integration including solution steps

- Solving mathematical equations

- Vector and matrix calculations

Abakus-Diff is a free version of Abakus with reduced functionality:

You can calculate derivatives of mathematical functions including solution steps.

For example, the command "differentiate + trace" applied to the formula

"x*sin(x)" with variable "x" yields the following output:

diff(x*sin(x),x)

# Differentiate product: (f*g)' = f'*g+f*g'

diff(x,x)*sin(x)+x*diff(sin(x),x)

# diff(x,x) = 1

1*sin(x)+x*diff(sin(x),x)

# Table

1*sin(x)+x*cos(x)

# Simplify

sin(x)+x*cos(x).

Moreover Abakus contains a special editor for mathematical formulas.

So you can enter even complex expressions very fast.

At the moment, the following functions are supported:

sin, cos, tan, cot (trigonometric functions),

arcsin, arccos, arctan, arccot (inverse trigonometric functions),

sinh, cosh, tanh, coth (hyperbolic functions),

arsinh, arcosh, artanh, arcoth (inverse hyperbolic functions),

sqrt (square root),

crt (cubic root),

exp (exponential function),

ln (natural logarithm),

abs (Betrags function),

sgn (signum function).

Feasible operators are '+' (addition), '-' (subtraction),

'*' (multiplication), '/' (division), and '^' or '**' (power).

## Abakus-Func

Abakus-Func is a computer algebra program which performs symbolic calculations for mathematical functions.

The current Android version 1.0 contains the following features:

- Calculate function values

- Determine exact zeros, singularities, extremal points, and turn points

- Calculate symbolic limits

- Graphical representation (2D and 3D).

As an example, Abakus-Func yields the following exact results for the function f(x) = x/(x+1)^2+2.

Zeros: x = -2, x = -1/2;

Singularities: x = -1;

Extremal points: Maximum (1,9/4);

Turn points: (2,20/9).

You can easily check the symbolic results by viewing the plot of the function. Several functions can be displayed simultaneously within the graphical window. You can select different colors for the individual functions. For functions with two variables, Abakus-Func generates a 3D-like graphical representation.

Moreover Abakus-Func contains a special editor for mathematical formulas. So you can enter even complex expressions very fast.

## Abakus-Equa

Abakus-Equa is a computer algebra program which performs

symbolic and numerical calculations on mathematical equations.

symbolic and numerical calculations on mathematical equations.

The current Android version 1.0 contains the following functions:

- Exact solution of linear and non-linear equations

- Numerical solution of linear and non-linear equations

- Exact solution of systems of linear equations

For example, the input "ln(x+4) = 0" with variable "x" yields the output "x = -3".

The equation "7*cosh(x) = sinh(x)+9" resolves to "x = ln((9-sqrt(33))/6); x = ln((9+sqrt(33))/6)".

For the system of equations "x+2*y = 3; 4*x+5*y = 7",

Abakus-Equa calculates the exact solution "x = -1/3; y = 5/3".

The variable system "x+a*y = 2; x-y = 0" resolves to "x = y = 2/(1+a)".

Moreover Abakus-Equa contains a special editor for mathematical formulas.

So you can enter even complex expressions very fast.
