push_tan
(EStackIndex
k
)
Category(ies):
Math
Description:
Pushes onto the estack the internally-simplified tangent of the expression
indexed by
k
. The only trigonometric tag that internally-simplified results
can contain is SIN2_TAG or (if IS_COLLECT_KERNELS) TAN_RAD_TAG,
both of whose arguments are always in radians. When
k
indexes a square
numeric matrix, pushes the Float matrix tan computed via
tan(eigenvalues).
Inputs:
k
— Indexes the top tag of an internally-simplified algebraic expression,
algebraic comparison, or aggregate thereof, with angles measured
in radians.
Outputs:
None
Assumptions:
None
Side Effects:
None
Availability:
On AMS 2.02 and higher.
