HP Prime Graphing Calculator - Manual (Page 405)

Functions and commands 401
median_line Draws the median line through A of the triangle ABC.
median_line((Pnt or Cplx(A)),(Pnt or
Cplx(B)),(Pnt or Cplx(C)))
Example:
median_line(0,8i,4)
draws the line whose equation
is y=2x; that is, the line through (0,0) and (2,4), the
midpoint of the segment whose endpoints are (0, 8) and
(4, 0).
member Tests if an element is in a list or set. If the element is in the list
or set, returns 1+ the index of the first occurrence of the
element. If the element is not in the list or set, returns 0.
member(Elem(e),(Lst(l) or Set(l)))
Example:
member(1,[4,3,1,2]) gives 3
midpoint Draws the midpoint of the line segment AB.
midpoint((Pnt or Cplx(A)),(Pnt or Cplx(A)))
Example:
midpoint(0,6+6i)
returns
point(3,3)
MINREAL Returns the minimum real number that the HP Prime is capable
of representing: 1E4–99.
MKSA Converts a unit object into a unit object written with the
compatible MKSA base unit.
mksa(Unit)
Example:
mksa(32_yd)
returns
29.2608_m
modgcd Uses the modular algorithm to return the greatest common
divisor of two polynomials.
modgcd(Poly,Poly)
Example:
modgcd(x^4-1,(x-1)^2)
gives
x-1
