Description:
ABAKUS is a computer algebra program which performs not only
arithmetic but even symbolic calculations of mathematical formulas.
The current Palm version 2.0 contains the following functions:
Exact arithmetic calculations:
Exact calculation of integer numbers of "randomly big"
size
Calculation of real numbers with "randomly large" digits
Exact calculation of fractions
Least common multiple, greatest common divisor
Factorial, binomial coefficient
Prime numbers, prime factor separation, divisor set
Transforming mathematical formulas:
Simplify, multiply, and factorize formulas; building the common
denominator
Normalize, divide, and factorize polynomials; separate into
partial fractions
Discussing mathematical functions:
Calculate function values
Zeros, singularities, extremal points, turn points
Differentiation, integration (even with solution steps)
Calculation of limits
Graphical representation (2D and 3D)
Solving mathematical equations:
Exact and numerical solution of linear and non-linear
equations
Exact solution of systems of linear equations
Vector and matrix calculations:
Simplify and invert matrices
Calculate determinates, Eigenvalues, and Eigenvectors
The free demo version allows you to test all functions of ABAKUS
for a certain input.
For example, the function "integrate + trace" applied to the
formula "xsin(x)" with variable "x" yields the following
output:
int(xsin(x),x)
Partial integration:
int(u(x)v'(x),x) = u(x)v(x)-int(u'(x)v(x),x)
u = x, v' = sin(x) => u' = 1, v = -cos(x)
-xcos(x)-int(-cos(x),x)
int(cf(x),x) = cint(f(x),x)
-xcos(x)-(-1)int(cos(x),x)
Table
-xcos(x)-(-1)sin(x)
Simplify
-xcos(x)+sin(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
func.s),
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).
Version overview:
V1.0: Initial release
V1.1: Minor bug fixes
V1.2: Bug fix in integration of rational functions;
Improved formula editor
V2.0: Additional functionality:
