Graphing calculator
RICalc is an essential Graphic calculator for maths.
You will find the Graphing calculator invaluable whether your are at
high-school, at university or regularly deal with mathematics.
It is comprehensive, advanced and yet easy to use.
With RICalc you concentrate on the maths, not on the calculator.
It is fun and simple to use with no cumbersome and complicated buttons.
General calculus, algebra, derivatives, integrals and function plotting is
simple in RICalc.
With the Graphic calculator you have all the essential tools to solve and graph equations.
- Solve an equation at point x.
Enter a one-dimensional algebraic equation and solve it for a given value.
Retrieve previous equation from a list of the last 100.
