With this powerful easy-to-use graphing calculator/scientific calculator you can graph functions using both Cartesian and polar coordinate system.
• 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.)
• Polar: f(θ) = 3sin(2θ) intvl=(0, 2π). (Use x for θ; the calculator replaces x's by θ's when you select polar coordinate system).

You can use the following in your expressions
• Basic algebraic operations
• Trigonometric functions and their inverses (RAD and 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 press the ? mark for more details.

Other features
• With this scientific calculator you can calculate complex numbers expressions. Example: (2+3i)^i+4∠(π/6). You can use i or j for the imaginary unit.
• Generate table of values.
• Degrees and Radians mode
• Calculate definite integral, area and arc length.
• Units Converter - convert units of length, mass, time,... .
• Change background color of the calculator.

You may need to upgrade to the full version of the graphing calculator to use the following features
• Graph parametric equations and point sets (Cartesian/polar).
• Graph several functions, parametric equations and point sets on the same coordinate system.
• Curve fitting and linear regression lines: find and graph the polynomial function of the least degree that passes through all the given points; find and graph the line that fits best the given point set according to the least squares criterion.
• Calculate derivatives (symbolic) of functions and parametric curves and graph them.
• Solve f(x) = 0 to find all the x-intercepts (zeros or roots of a function) on an interval without guesswork. .
• Scientific, engineering and fixed point notations.


When no interval is specified:
• The graphing calculator automatically appends a default interval to the function and parametric expression and draws the graph on that interval.

Graph MULTIPLE expressions on the same coordinate system:
• First long press 'Graph'. (Premium version only).

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.

On this graphing calculate most keys are assigned a second functionality by long pressing. For example

• Long press of ^ (power) sign: Appends 'intvl=(' to the expression if it is not already appended or deleted. Long press of decimal point inserts comma to separate the end-points.

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

    Once you understand the layout, which doesn't take too long, this is very useful foe what it does! The screens and graph are nice to navigate! If you have need for a basic graphing app, this is great! I would think that the premium version would deliver its promised features just as well. Very nice.
