About this app

This graphing calculator features graphing capabilities offered by no other graphing calculators and its unique advanced user-friendly interface makes graphing and calculations as intuitive as possible.

Calculate and graph mathematical expressions containing
• basic algebraic operations
• linear and polynomial functions
• power functions, x^r and E(x)
• trigonometric functions and their inverses
• hyperbolic functions and their inverses
• exponential, e^x and exp(x), and logarithmic functions
• factorial
• the Gamma function, Γ
• the Psi functions, ψ
• absolute value and step functions: round, floor, ceil

This is the only graphing calculator that seamlessly switches between the Cartesian and polar graphs by changing the coordinate system.

You can draw the Cartesian & polar graphs of
• functions
• parametric equations
• point sets

NOTE: to graph the expression in focus press the ‘graph’ button. To graph one or more selected expressions simultaneously, press the ‘Graph’ (capitalised) button.

Calculate
• all the x-intercepts of the graph of a function on an interval with a single click by solving the equation f(x) = 0.
• points of intersection of the graphs of two functions.
• symbolic first and second order derivatives of functions and parametric equations and graph the derivatives.
• definite integrals
• area under (or enclosed by) the the Cartesian and polar graphs of functions (or parametric curves)
• arc length of Cartesian and polar graphs.

It is also the only graphing calculator capable of
• finding and graphing the polynomial of the least degree passing through a set of points.
• finding and graphing the best line (linear regression line or least squares line) that fits a set of points according to Gauss' Least Squares Criteria.

Other Features
• This calculator is also capable of calculating complex numbers in standard, polar or any other forms.
• The calculator can display a table of values for functions and parametric equations even with complex expressions.
• The calculator can display the result in scientific, engineering and fixed point notations.
• Calculate relevant expressions in degrees or radians mode.

The calculator also comes with an easy-to-use units converter (Time, Mass, Length, Velocity, and many more), and list of constants from various fields of sciences which can be used in your calculations.

Detailed built-in instruction is provided in the menu accompanying this graphing calculator.
