This program provides commonly used SI Imperial engineering unit conversions.

Converts back and forth between Gregorian (common) calendar dates and Julian dates.

Combinations and permutations (Cy,x and Py,x) calculator.

To provide a quick method with assigned buttons to change the display with the user’s choice of number of digits, from 0-9 and “All”.

This program assists in debugging by bringing a number of needed functions to the keytops. Thus, the steps in a program can be simulated by pressing keys.

To find the position of the Moon given the date and time.

SOLVER is a simple root finder program for the MathU Pro. It uses the “regula falsi” method, also called the secant method, to find the roots of the function. It has some improvements beyond the basic routine to speed-up the convergence of the algorithm. However it can be fooled by certain functions whose slope near to a root is so flat that the method never converges. Even though the algorithm is not full proof, it could find positive roots accurate enough for many applications.

This is a rather simple program that uses the “show” line on virtually EVERY function in the MathU Pro standard program that does not already have an output on the show line. I also included the “PS” one that uses the “User flag” so that the user knows by the “show” line what the setting is for the “PS” function.
