Formulae 1 by Poliplus Software for Zaurus

Educational mathematical Software. Check it out at MyZaurus.com


Formulae 1 (F1) is a powerful and easy to use Computer Algebra System
designed specially for the teaching and exploration of
mathematics. F1 gives the user the ability to see intermediate steps of
calculations as well as final answers. The step feature has
tremendous pedagogical value that users will come to appreciate over and
over again.

While there are several different numerical based calculator programs
for PDAs, there is nothing really that comes close to the
mathematical capabilites of F1. Transform your PDA into the next
generation handheld Mathematics system designed to get
answers and see steps. If you are a student, this is a must have
application.

F1's User Interface was custom designed to optimize the use of the small
screen area of the device. Most of the screen area is
available to view and manipulate math expressions, unlike other
calculators where most of the screen is populated by buttons.

Feature set of Formulae 1:

     Simple to use and well organized Graphical User Interface featuring
tabs, buttons, palettes, command folders and
     extensive built-in help system with tons of sample mathematical
problems.

     Fast automatic simplification of expressions containing symbols and
functions.

     Correct 2D display of mathematics including proper use of symbols
such as fraction divider, absolute value, radicals,
     derivatives, integrals, etc.

     Math Editor builds expressions graphically as they are typed
providing an intuitive environment to deal with mathematics.

     Powerful command center via Go and Step. Just build a query and
press Go to obtain the final answer to the query or
     step to obtain the next step in the calculation process. With these
two commands, all the user needs to know is how to
     type a query (problem) in and from there on the system will solve
it and show intermediate steps as required by the user
     automatically.

     Powerful automatic Solve facility capable of solving symbolically
in one shot or via steps, equations containing absolute
     value, radicals, polynomials, inequalities and systems of
equations.

     Main commands for factorization, evaluation (turning a symbolic
expression into a number) and simplification of
     expressions.

     Trigonometric Functions: sin, cos, tan, csc, sec, cot, asin, acos,
atan, acsc, asec and acot. Special stepwise emphasis
     was placed here to deal with removing extra revolutions (in radians
and degrees) as well as folding trigonometric
     expressions in quadrants II, III and IV into quadrant I, this has
great pedagogical value to students learning trigonometry.

     Logarithmic Functions: ln, log, log of base b and exp.

     Miscellaneous Functions: mixed fractions conversion, absolute
value, square root, nth root, factorial, exponential
     notation, imaginary numbers and user defined functions.

     Calculus support: Derivatives, Integrals, Integration by Parts and
Integration by Variable Substitutions. Stepwise
     Integration highlights automatically specific integration
techniques such as using Partial Fractions expansion, long division
     and integration by parts or a special variable substitution.

     Matrix Support: Full Matrix Arithmetic, Row Operations and Matrix
Functions including (determinant, adjoint, matrix
     inverse, transpose and others). Of special mention here is the
stepwise calculation of matrix inverse by using row
     operations. The system will automatically show row operations used
to inverse any matrix (even symbolic ones) and then
     it will perform the actual row operation. Tremendous Pedagogical
value to users.

     Polynomial Support: permutations, combinations, grouping, complete
the square, splitting fractions, long division and
     partial fractions.

     Powerful Variable and Function Isolation that allows the user to
manually manipulate equations step by step.

     Easy object based graphing. Unlimited plots can be removed or added
at will.
