With this tool it will be able to write down simple equations like x^2 +2*x -2 or for example 1+sin(x)/x and so on. The solver builds the results between a given range and a given step-size. A double-array will be returned.
This Java-program uses GnuOctave to solve the results of the equations. JFreeChart ist the Java-API to plot the xy-charts.

sin(x), asin(x), cos(x), acos(x), tan(x), atan(x)
Java Runtime - get it from Java™
JFreeChart - it's also implemented as jar (very good and fast charting API for Java)
