Geometry 181
Example:
areaat(circle(x^2+y^2=1), point(-4,4))
displays “acircle(x^2+y^2=1)= π” at point (-4, 4))
areaatraw
Works the same as areaat, but without the label.
distanceat
Used in Symbolic view. Displays the distance between 2
geometrical objects. The measure is displayed, with a label,
at the given point in Plot view.
distanceat(object1, object2, point)
Example:
distanceat(1+i, 3+3*i, 4+4*i) returns “1+i
3+3*i=2√2”
at point (4,4)
distanceatraw
Works the same as distanceat, but without the label.
perimeterat
Used in Symbolic view. Displays the perimeter of a polygon
or circle. The measure is displayed, with a label, at the given
point in Plot view.
perimeterat(polygon, point) or
perimeterat(circle, point)
Example:
perimeterat(circle(x^2+y^2=1), point(-4,4))
displays “pcircle(x^2+y^2=1)= 2*π” at point (-4, 4)
perimeteratraw
Works the same as perimeterat, but without the label.
slopeat
Used in Symbolic view. Displays the slope of a straight object
(segment, line, etc.). The measure is displayed, with a label,
at the given point in Plot view.
