Graph Plotter
— Instrument which helps you to create a two-dimensional plot of functions easily and quickly.
— You can view several functions’ graphs on the same worksheet.

Advanced Scientific Calculator
— Calculator, which can do real and complex computations.

Analysis
— Limit — Attempts to compute the limiting value of function f(x) as it’s argument x approaches x0, possibly infinity, or —infinity.
— Differentiation — Computes the derivative of the function f(x) with respect to x.
— Numerical Differentiation — Computes the first, second, or higher–order derivative of the function f(x) with respect to x at x0.
— Definite Integration — Computes a definite integral of the expression f(x) with respect to the variable x over the straight line from a to b (finite numbers).

Matrix Operations
— The main matrix operations such as addition, subtraction, multiplying, computing the inverse and determinant of the given matrix are frequently used but quite complicated and laborious.

Equation Solver
— Solve the arbitrary equations, systems of linear equations numerically.
— Solve initial value problems for ordinary differential equations.

Custom Functions And Constants
— This utility gives you an opportunity to record an arbitrary formula, give it a unique name and then use it like standard functions such as sin(x) or ln(x). So, if you need to use some function or formula often, this utility will certainly please you.
— Support for Multidimensional user-defined functions.
— You can record constants and use them in your formulas.

History
— History provides quick access to the last performed computations.

Functions Menu
— This instrument will help you to enter data, parameters, functions, custom functions, constants and other information quickly and conveniently.
