Numworks: Update to Software Version 15.5

Numworks: Update to Software Version 15.5 

On May 10, 2021 updated their software of the Numworks graphing calculator to Version 15.5.0.   

New Features

Some of the new features include:

Calculation Mode: 

*  The Calculation mode gets a new section:  Vectors.  The available functions are dot, cross, and norm.  

*  The ref and rref functions are added to the Matrices section.

*  When the results is a matrix, we can go up into the history, select the three dots next the matrix.  This gives us the additional results:  determinant*, inverse*, row echelon form, reduce row echelon form, and trace* (*for square matrices only)

* Like functions, sequences can be evaluated from outside the respective graphing (Sequence) mode.  

Functions Mode:

*  The graph can be auto-scaled.  


*  The gcd and lcm commands can accept more than two arguments.  

*  Even though they can't be used in algebraic expressions, the °C and °F units are added to the units menu.  

*  Many imperial (United States) units are added such as ft, acre, lb, and gal.  

You can find all the details here:

I have to remember than Numworks does a lot more than Python.
