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 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. • Use any of the 400+ pre-defined functions:
Math, Trigonometry, Statistic, Financial, Conversion, Logical, Text, Date, Geometry and Miscellaneous functions. Use your own saved expressions. • Get a Report on an equation for a given interval.
Type an algebraic equation, define point a and point b, and get a summary for:
Root(s), Extrema, Intercept, Distance and Table points. Solver
• Solve equations with Root Finder numeric methods.
Find the root of an equation with choice of numeric methods:
Brent, Ridders, Newton-Raphson, Bisection, False position, Secant ...
Find the Extrema, the Minimum or the Maximum of a function. Derivative
• Calculate Derivatives with choice of numeric differentiation methods.
Stirling, Newton, Ridders central, 3-5 points, forward, backward,
1st, 2nd, 3rd ... Nth derivative ... + 3 point high-precision derivative. Integral
• Calculate Integrals with choice of numeric integration methods.
Romberg (adaptive), Guass 3 & 5 points, Simpson 3/8 & 1/3,
