RootFinder 1.0   (details) 48   EN   4KB/1KB
Rootfinder uses two numbers, the first being the number you're finding the root of (the radicand) and the second being the nth root's n (the index). Displays the simplified root in a format with the factored out numbers multiplied by the remaining radicand. The index is noted before the radical symbol by an up arrow.

Symbolic Vector Library 1.1   (details) 48   EN   7KB/6KB
SYMVEC (SV) is a User RPL-written library of symbolic vector functions for use in mathematics and the sciences. Support is given for Cartesian, Cylindrical, and Spherical polar coordinates, as well as general orthogonal coordinates (whose definitions are supplied by the user). The current coordinate mode is sensed automatically by the library, and the user may override the sensing and force execution in a chosen coordinate system. The SV functions are, for the most part, usable in algebraic expressions (although their inputs may not be -- the intention is for simplification of programming).

Two-Stage Least Squares Program   (details) 48   EN   2KB/2KB
TSLS computes four things and puts them on levels 1-4 on the stack. On level 4 is the degrees of freedom of the t values. On level 3 is a vector of the t values for the computed coefficients. On level 2 is a vector of the standard errors of the computed coefficients. On level 1 is a vector of the computed coefficients of the form [Alpha, Beta, Gamma], where Alpha is the value of the intercept, Beta is the k coefficients of the Y1 matrix, and Gamma is the i coefficients of the X1 matrix.
