Arithmetic Operations

To enter numbers, coordinates or equations (4.2) you may use arithmetic expressions with parentheses. The following operations are available:

operation | input
addition | `+`
subtraction | `-`
multiplication, scalar product | `*` or space
division | `/`
potentiation | `^` or 2, 3
factorial | `!`
Gamma Funktion | `gamma( )`
parentheses | `( )`
x-coordinate | `x( )`
y-coordinate | `y( )`
absolute value | `abs( )`
sign | `sgn( )`
square root | `sqrt( )`
exponential function | `exp( )`
logarithm (natural) | `log( )`
cosine | `cos( )`
sine | `sin( )`
tangent | `tan( )`
arc cosine | `acos( )`
arc sine | `asin( )`
arc tangent | `atan( )`
hyperbolic cosine | `cosh( )`
hyperbolic sine | `sinh( )`
hyperbolic tangent | `tanh( )`
antihyperbolic cosine | `acosh( )`
antihyperbolic sine | `asinh( )`
antihyperbolic tangent | `atanh( )`
greatest integer less than or equal | `floor( )`
smallest integer greater than or equal | `ceil( )`
Runden | `round( )`

For example, the midpoint M of two points A and B might be entered as `M=(A+B)/2`. The length of a vector v might be calculated using `l=sqrt(v*v)`.

We see that you can do calculations with points and vectors as well in GeoGebra.
