About this app

• Graph up to six functions, parametric curves and point sets (scattered plot) using the Cartesian or polar coordinate systems.

• Curve fitting / linear regression line: when plotting points, this graphing calculator is the only known graphing calculator that can also find and graph the polynomial of the least degree passing through all the points and also find and graph the best line that fits the points according to the Gauss' least squares criterion.

• Find all the x-intercepts of the graph of a function on an interval.

• Find the points of intersection of the graphs of two functions.

• Calculate symbolic derivatives of functions and parametric curves and graph the derivatives.

• Calculate definite integrals, area under (or enclosed by) and arc length of the graph of functions or parametric curves in both Cartesian and polar cases.

• Generate table of values.

• Choice of scientific, engineering and fixed point notations.

• Choice of background color for the calculator.

If your expression is incomplete or if you make a syntax error touch the ? mark; this intelligent graphing calculator gives you feedback by precisely indicating the error.

This calculator also lets you calculate with expressions containing complex numbers in all forms, such as, (1+2i)^i+3sin(4-5i)∠(π/4). The result is given in standard, polar and other forms. (you can use i or j for the imaginary unit.)

Syntax ( by examples)
The graphing calculator, for convenience, automatically appends a default interval to function and parametric expressions and graphs or does calculations over the interval. You can change the endpoints of the interval, of course.

• Function: f(x) = xsin(2x) intvl=(-∞, ∞). (You don't have to type in the interval 'intvl=(-∞, ∞)'; the graphing calculator appends it when you press the graph button.)

• Parametric: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). Note: enter x(t) and y(t) separated by a comma -- no enclosing parentheses around x(t), y(t).

• Point set: -1,2; 3,4/5; 6,7; Note: enter the point (x,y) as x,y;

The calculator also provides a very useful and intuitive units converter for converting units of mass, length, time and many more quantities.


All of the above with more details are included in the built-in Instruction of this Graphing Calculator.
