Of course, that’s free as in no charge, not free as in open source.

To start with, HP has a free app that runs on Windows or Mac that works just like the calculator. But if you can’t justify a $150 calculator, there are some cheap and even free options out there to get the experience. It is hard to call it a calculator since the latest variant has a 528 MHz ARM Cortex A7, 256 MB of RAM, and 512 MB of ROM. Today’s students are more likely to have a TI or Casio calculator, but HP is still in there with the HP Prime. The slide rule sword gave way to calculators hanging from your belt loop, and for many engineers that calculator was from HP. Well, really it was a slide rule hanging from your belt, but it sounds cooler to call it a sword. Don’t really know what that means.There was a time when being an engineering student meant you had a sword. I can’t think of (off the top of my head that is) a single non-engineer that uses RPN. I know many engineers that use HP calculators for the RPN way of doing calculations. (kind of hard to explain in words but showing the stack after each input makes it clear) Think of RPN as a stack of numbers (typically 4 numbers) that you are entering numbers on the bottom of the stack and when you enter a operator, you are telling what it is to do with the bottom 2 numbers in the stack.

In the above example, after you enter the + sign when using RPN, you will see that the value within the parentheses is 10. Algebraic input does not provide any intermediate results and you don’t get any feel as to the relative magnitude of the individual parts of any longer calculations. I find that knowing the relative values of some of the intermediate results valuable in understanding what is going on in the expression (and therefore the physical problem you are working on). Probably a backhanded comment.Īlgebraic input is just like the equation reads (7+3)*12=Įntering the same expression in RPN would be: 7, enter, 3, +, 12, *Īlthough the RPN way of doing calculations looks crazy, it does force you to look at the relationships of the numbers in the expression and you do get to see the intermediate results as you are performing the calculation. How it got to be called that is unknown to me. After a certain point it makes more sense to do assignments with MATLAB and/or EES rather than fiddle with a graphing calculator.Īs a CivE keep in mind your FE exam for which the ti-36x is the most powerful calculator allowed, so you want to get intimately familiar with it now. The 89 is also the best for speed in expanding/factoring polynomials (useful in DiffEq). Out of 27 math/science/engineering courses so far I can almost count on one hand the number of exams where a graphing calculator was required/more useful.

3x3 with complex conjugates) and any exam where it was quicker to solve for min/max using the graph or just to see the graph. That said, I used an 89 for solving larger/more complicated matrices in linear algebra ( i.e. It has a ridiculous amount of built-in capabilities and has served me well for any course that has allowed or required a calculator. Speed is the name of the game in my opinion and I have yet to find anyone with an 83 or 89 who can beat me in terms of getting the answer vs my ti-36x pro.
