a function-value table, x-axis intersections and an interactive (dynamic) function graph display for
f(x) = P9(x) = a*x9 + b*x8 + ... + h*x2+i*x+j and g(x) = P9(x)
or sin(z), cos(z), tan(z) and sqrt(z) (for a functional combination z(x)
with z := f or z := f / g ).
Expansion of '(x+a)*(x+b)*(x+c)*...' to a polynome of degree 9 (max.)
and symbolic computation of f(x)=0 for f2(x) = P2(x) = h*x2+i*x+j .
Integrated help-system,vector,fraction and percentage computations and a tool to solve
'2*2' and '3*3' systems of equations step by step or all at once.

and some SonyEriccson and BenqSiemens devices.
note: depending on your cellphones operating system the .jar file will possibly be
moved to a games or application directory automatically
after you have copied the file to the root directory of the phone.
