bounded_function

Argument returned by the limit command, indicating that the function is bounded.

breakpoint

Used in programming to insert an intentional stopping or pausing point.

canonical_form

Returns a second degree trinomial in canonical form.

canonical_form(Trinomial,[Var])

Example:

canonical_form(2*x^2-12*x+1) gives 2*(x-3)^2- 17

cat

Evaluates the objects in a sequence, then returns them concatenated as a string.

cat(Object1, Object2,…)

Example:

cat("aaa",c,12*3) gives "aaac36"

Cauchy

The Cauchy probability density function. Computes the probability density of the Cauchy distribution at x,

given parameters x

and a. By default, x

= 0 and a = 1.

cauchy([x

], [a], x)

Example:

cauchy(0,1,1) returns 0.159154943092, as does cauchy(1)

Cauchy_cdf

Cumulative Cauchy probability density function. Returns the lower-tail probability of the Cauchy probability

density function for the value x, given parameters x

and a. With the optional parameter x

, returns the area

under the Cauchy probability density function between x and x

cauchy_cdf(x

, a, x, [x

])

Examples:

cauchy_cdf(0,2,2.1) returns 0.757762116818

cauchy_cdf(0,2,2.1,3.1) returns 0.0598570954516

Cauchy_icdf

Inverse cumulative Cauchy probability density function. Returns the value x such that the Cauchy lower-tail

probability of x, given parameters x

and a, is p.

cauchy_icdf(x

, a, p)
