Comparison of HP 10C, HP 11C and HP 15C Scientific Calculators

A comparison of three classic HP scientific calculators from the Voyager series.

In this video I talk through progressive functionality of the HP 10C, 11C and 15C scientific calculators. I talk through Reverse Polish Notation (RPN) and the basic scientific functions. I then move on to talking through the linear regression capabilities of the 10C and keystroke programming and an example program that generates the Fibonacci series. I move onto the improved programming functionality on the 11C such as the index register and show an example of how loop control works. I also demo the 15C's ability to solve roots of equations and do numeric integration, as well as it's support for complex numbers and matrices. The video finishes with a summary of all three of the models and talk about which is my personal favourite.
