Why this blog

This blog is intended to save time during the PE exam by taking advantage of the programming capabilities of the HP calculators allowed in the exam.

During my undergrad studies I had HP 48SX and 48GX which I programmed with a variety of engineering programs that helped me immensely during my exams.

As I advance in my studies for the PE exam this October/2011 I'll post some small programs/formulas and examples that I believe are standard in the exam.

RPN mode

First things first. It is clear that we own HP calculators because we are familiar with the Reverse Polish Notation (RPN). Programs are better in RPN mode than the traditional algebraic mode because they execution is faster and it uses less memory.
