Appendix A: System Routines - Math 775 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. Inputs: i - Index of the top tag of an internally-simplified algebraic expression, a comparison, or an aggregate thereof. vi - Index of the top tag of a variable. j, k - Indices of the top tags of internally-simplified algebraic expressions or aggregates thereof. Outputs: None Assumptions: None Side Effects: None Availability: On AMS 2.02 and higher. TI-89 / TI-92 Plus Differences: None See Also: did_push_anti_deriv, push_nint, push_arclen Example: void push_arclen (EStackIndex i, EStackIndex vi, EStackIndex j, EStackIndex k) { 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); } TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
