Push_Def_Int - Texas Instruments TI-89 Developer's Manual

Appendix A: System Routines — Math

push_def_int

Declaration: void push_def_int (EStackIndex i , EStackIndex vi , EStackIndex j ,
EStackIndex k )
Category(ies): Math
Description: Pushes onto the estack the definite integral of the expression indexed
by i , integrated with respect to the variable indexed by vi , from the
lower limit indexed by j to the upper limit indexed by k . If invoked via
push_internal_simplify, vi and i are simplified to deepest variable.
Moreover, i is simplified under the influence of a temporary such that
vi > j and vi < k when j < k .
i
Inputs:
vi
j, k — Indices of the top tags of internally-simplified algebraic
Outputs: None

Availability: On AMS 2.02 and higher.

{ Access_AMS_Global_Variables;
EStackIndex m, old_top = top_estack;
push_quantum_as_nonnegative_int (2u);
m = top_estack;
push_1st_derivative (i, vi);
replace_top2_with_pow (m);
add1_to_top ();
i = top_estack;
push_sqrt (i);
delete_between (old_top, i);
i = top_estack;
push_def_int (i, vi, j, k);
delete_between (old_top, i);
