Customer ratings and reviews for HP 50g Graphing Calculator

Rated 5 out of 5 by Excellent, my new favorite I've owned and loved an HP35, 45, 67, 41CV, 41CX, 48GX, and now a 50G. I had a 49G, didn't love it so much... I still own and use the 41CX and 48GX. I decided to buy the 50 to develop some programs for work, and I was attracted to the larger display and connectivity. I love it. It feels good in my hand, the keys have a good snap to them, and the color is much better than the 49. I can appreciate the location for the enter key, but it's taken some getting used to. All in all, a great calculator. January 13, 2013
Rated 5 out of 5 by A real tool for engineers and other professionals The 50G is much more than a calculator. I got mine in sophomore year of college when I took Circuits I and found out that my TI-84 couldn't handle matrices with complex numbers. The professor teaching that class was a die hard HP user. I didn't feel like spending another $100 or more on another calculator (the only other option was the TI-89 which I had used and didn't like) and he had convinced me that HP was the way to go. From the second I pressed the first key, I knew that this was the beginning of a different but great journey. Available Functions I appreciate the wealth of functions that are available on this machine, as well as the programming capabilities. It deals with complex numbers without a problem. I also use the equation solver all the time. The ability to solve an equation symbolically (using only variables, no numbers) is great too. Being able to take partial derivatives is nice (the math department knew that the TI-89 could take partials, and thus, was not allowed on exams, but had no idea what an HP 50G was). I could go on and on, but you get the idea. Graphing This part takes a little getting used to. If you were to plot the sine of x, as in, y = sin (x), you may not get what you would expect to see on a TI-84, but when you play around with the scaling and things, it actually makes more sense. 3D GRAPHING! WOW! Can anyone else's calculator do that (this was another math department lack of knowledge, 3D graphing was great for the chapter on surfaces in calc 3)? Practical Usage I can't count how many times I've used this baby to perform mesh analysis in a circuits problem (and do it faster than anyone else). I was also able to do Laplace Transforms faster. This calculator has also proved very useful in Electromagnetic Field Theory; finding curl and divergence of a 3D vector field is a snap! I once tried to transfer a program to my friend's 50G but forgot the cable. I then remembered that IT HAS INFRARED DATA TRANSFER! I can't imagine ever running out of memory, but having that SD card slot is great too. Being able to use units in a calculation is a very useful feature. PROS Has RPN (and Algebraic too, if you don't want to learn RPN) Feels like a real tool rather than a cheap calculator Comes with a faux leather case, not a cheap hard cover Has an extremely large library of functions covering every discipline (and a constants library too!) Has IR data transfer (seldom found in other calculators) Can be programmed in C Is comparable in price to similar models (but is WAY better) CONS The numeric equation solver cannot deal with complex numbers The ENTER key is not double sized like classic HPs (but who really cares? If THAT'S your deal breaker, you've got problems) The case does not have a belt loop (I stitched my own on) All in all, I consider this to be the best purchase I have made in my college career. I think that should say enough. If you're on the fence, give HP calculators a try, the only regret you'll have is that you didn't try them sooner! January 11, 2013
Rated 1 out of 5 by This is, sadly, not your father's HP I have used HP calculators for the last 20 years, as a college student and as a practicing engineer. My first was a 48SX that lasted me through engineering school and into the workplace as a field engineer. When it died (the field is hard on equipment) I upgraded to the 48GX. Both were great, well built pieces of equipment for the serious user. My 48GX was lost when our offices burned down, so I replaced it with what was available, the 50G. Ostensibly, it performs the same functions as the other two, but the quality has gone downhill in a noticeable way. It is a cheap imitation designed by someone (or group of people) who have never used a calculator in the real world. It lacks the substantial feel that its predecessors had, and because of that sits in my desk drawer collecting dust. I will never buy another HP calculator again until management reverses course and resumes producing serious tools. December 28, 2012
Rated 5 out of 5 by The best calculator The best calculator for a scientist or engineer. I like to see a new model with some new features and the quality of this product. October 30, 2012
Rated 4 out of 5 by this product is ok I was trying to replace my 48G and I needed it fast. the 50 has some nice features, the case is lighter the enter key is in a different place. and I have only had it for a while I'm still learning. October 10, 2012
Rated 5 out of 5 by Great calculator I bought my first HP, a 15C, back in the mid 80's. That's where I first discovered RPN, and that s why I stick with HP. Currently have a 48G I got at a flea market. 25$ and looks mint! The 50G is the nicest, most powerful calculator I've ever had. I will never be without on. I teach Algebra 2, and love to show my TI 84-wielding students the 50G. June 6, 2012
