Innovative, exceptionally powerful graphing calculator with an intuitive and user-friendly interface.

Main features

• Graph multiple functions, parametric equations and point sets simultaneously.

• Polar graphs of the above.

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

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

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

• Curve fitting and linear regression lines: When plotting a point set, the graphing calculator can also find and graph the polynomial of the least degree containing all the points. It can also find and graph the least-squares line - which best fits the given set of points. Or, you can just connect the points with straight lines to form a polygon, for example.

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

• Generate table of values for functions and parametric equations.

• Calculate definite integrals of functions or parametric curves in both Cartesian and polar cases.

• Calculate area under (or enclosed by) the graphs of functions (or parametric curves) in both Cartesian and polar cases.

• Calculate arc length of the graphs of functions or parametric curves in both Cartesian and polar cases.

• Choice of scientific, engineering and fixed point notations.

• Calculate expressions containing complex numbers, such as, (2+3i)^i+5∠(4). You can use i or j for the imaginary unit. The result is given in standard, polar and other forms.

• Choice of background color for the calculator.

You can use the following in your expressions

• Basic algebraic operations

• Power functions

• Trigonometric functions and their inverses (RAD, DEG)

• Hyperbolic functions and their inverses

• Exponential and logarithmic functions

• Factorial, the Gamma function Γ and Psi function Ψ.

• Absolute value and Step functions.

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

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. You can change the end-points as desired.)

• 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; 2,3; 4,5; 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.

When viewing the Graphs:

• Touch Polar on the upper right corner of the graphing area to draw the graphs in polar coordinate system.

• Drag the graphs. To center the graph on the screen, touch the coordinate indicator on the top left corner of the graphing area.

• Touch ++ or -- on the lower right corner of the graphing area to zoom in or out.

• Touch the lower left corner of the graphing area (where the caption is) to reset zoom.

All of the above with more details are included in the built-in Instruction menu accompanying this graphing calculator.
