Appendix A: System Routines - Math 809 push_nint Declaration: void push_nint (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 with respect to the variable indexed by vi going from the expression indexed by j through the expression indexed by k, computed via quadrature. If invoked via push_internal_simplify, vi and i are simplified to deepest variable, and the simplification of i is done under the temporary influence of SET_PARTIAL_SIMPLIFY to avoid costly polynomial expansions, polynomial GCDs, etc. Inputs: i - Indexes the top tag of an internally-simplified algebraic expression or an aggregate thereof. vi - Indexes the top tag of a variable. j, k - Indices of the top tags of internally-simplified algebraic expressions. 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_def_int, push_arclen Example: push1(); k = top_estack; push0(); j = top_estack; push_quantum (8u); /* Push integration variable and integrand x */ push_nint (top_estack, top_estack, j, k); /* Pushes 0.5 */ TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
