210 Functions and commands
tail Given a list, string, or sequence of objects, returns a vector
with the first element deleted.
tail(List) or tail(Vector) or tail(String) or
tail(Obj1, Obj2,…)
Example:
tail([3 2 4 1 0]) gives [2 4 1 0]
tan2cossin2 Returns an expression with tan(x) rewritten as (1–cos(2*x))/
sin(2*x).
tan2cossin2(Expr)
Example:
tan2cossin2(tan(x))
gives
(1-cos(2*x))/sin(2*x)
tan2sincos2 Returns an expression with tan(x) rewritten as sin(2*x)/
(1+cos(2*x)).
tan2sincos2(Expr)
Example:
tan2sincos2(tan(x))
gives
sin(2*x)/(1+cos(2*x)
transpose Returns a matrix transposed (without conjugation).
transpose(Matrix)
Example:
transpose
returns
trunc Given a value or list of values, as well as an integer n, returns
the value or list truncated to n decimal places. If n is not
provided, it is taken as 0. Accepts complex numbers.
trunc(Real, Integer) or trunc(List, Integer)
Example:
trunc(4.3)
gives
4
tsimplify Returns an expression with transcendentals rewritten as
complex exponentials.
tsimplify(Expr)
Example:
tsimplify(exp(2*x)+exp(x))
gives
exp(x)^2+exp(x)
