GRAPHICS CALCULATOR
...FAQ...
-
To plot the curve of a function, enter the desired expression in standard mathematical notation using x as the variable. Multiplication is natural, so there's no need to put a multiplication operator between numbers and variables. The function plotter follows the common rules of math notation and order of operation. Expressions inside parentheses have increased precedence, while multiplication and division have higher precedence than addition and substraction. If there is any error in the expression typed, the formula will turn red until fixed.

To zoom the graph in or out, pinch with two fingers.
-
To pan the graph in real-time, drag it with one finger.
-
To plot several functions, separate their formula with a semi-colon ";"
Example: 3x ; cos(x+1)

To switch between plain calculator mode and graphing mode, press the MODE buttons.

To discover the coordinates of a local function extremum, double-tap over the target. A balloon will instantly appear, revealing the nature of the selected extremum ("minimum" or "maximum") and its computed coordinates as shown below.
