Push_Acosh - Texas Instruments TI-89 Developer's Manual

Appendix A: System Routines — Math

push_acosh

Declaration: void push_acosh (EStackIndex k )
Category(ies): Math
Description: Pushes onto the estack the internally-simplified principal branch of the
inverse hyperbolic cosine of the expression indexed by k . Thus the real
part of the result is in the range [0, ].
When k indexes a square numeric matrix, pushes the Float matrix acosh
computed via acosh(eigenvalues(matrix)).
Inputs: k — Indexes the top tag of an internally-simplified algebraic expression,
Outputs: None
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.
