randvector

Given an integer n, returns a vector of size n that contains random integers in the range -99 through 99 with

uniform distribution. With an optional second integer m, returns a vector lled with integers in the range (0,

m]. With an optional interval as second argument, lls the vector with real numbers in that interval.

randvector(n, [m or p..q])

ranm

Given one integer n, returns a vector of size n containing random integers in the range [-99, 99], with uniform

distribution. Given two integers n and m, returns an nxm matrix. With an interval as the nal argument,

returns a vector or matrix whose elements are random real numbers conned to that interval.

ratnormal

Rewrites an expression as an irreducible rational fraction.

ratnormal(Expr)

Example:

ratnormal returns

rectangular_coordinates

Given a vector containing the polar coordinates of a point, returns a vector containing the rectangular

coordinates of the point.

rectangular_coordinates(Vector)

Example:

rectangular_coordinates([1, π/4]) returns

reduced_conic

Takes a conic expression and returns a vector with the following items:

●

The origin of the conic

●

The matrix of a basis in which the conic is reduced

●

0 or 1 (0 if the conic is degenerate)

●

The reduced equation of the conic

●

A vector of the conic’s parametric equations

reduced_conic(Expr, [Vector])

Example:

reduced_conic(x^2+2*x-2*y+1) returns
