tan
function for its argument. The general
syntax for its use is
y = tan(x)
where x
is an n
-dimensional array of numerical type.
Integer types are promoted to the double
type prior to
calculation of the tan
function. Output y
is of the
same size and type as the input x
, (unless x
is an
integer, in which case y
is a double
type).
tan
function is defined for all real
valued arguments x
by the infinite summation
or alternately by the ratio
For complex valued arguments z
, the tangent is computed via
tan(x)
function over the interval [-1,1]
:
--> t = linspace(-1,1); --> plot(t,tan(t)) --> quit
