To compute usual arithmetical operations, use the symbols: (
,
)
, +
, -
, *
, /
,
^
(for exponentiation).
The available numerical functions are: abs(x)
,
sqrt(x)
, exp(x)
, ln(x)
,
sin(x)
, cos(x)
, tan(x)
,
asin(x)
, acos(x)
, atan(x)
,
deg(x)
(to convert radians in degrees), rad(x)
(to
convert degrees in radians).
There is one constant: pi
.
Next, the following number valued functions are also available:
abscissa(A)
or abscissa(u)
ordinate(A)
or ordinate(u)
distance(A, B)
or distance(A, l)
length(u)
or length(s)
radius(c)
major(cc)
minor(cc)
eccentricity(cc)
arg(cc, A)
arg
returns the argument of the image of A by a
projection on cc. The direction of the projection is the one of the principal
axis if cc is a parabola, of the center if cc is an ellipse, of the major axis
if cc is an hyperbola.
height(A, B, C)
Last, there are all the angle measure functions. The result is in degrees.
Eukleides handles directed angles, hence angle
returns a signed
number greater than -180° and smaller than or equal to 180°.
angle(u)
or angle(l)
or angle(s)
angle(cc)
angle(u, v)
angle(A, B, C)
