HP 50g Graphing Calculator (F2229AA#ABA)

The 50g features easy-to-use, powerful tools that students and professionals can rely on for years of performance, including built-in graphing functions, constants, and applications. This calculator also offers built-in lessons and step-by-step problem solving examples to help illustrate abstract concepts. Choose between efficient RPN (Reverse Polish Notation), Textbook, or Algebraic data entry and rest assured that expansive memory (with SD card slot) means the 50g can handle even the most complex calculations. Graphing features include 2-D function, polar, and parametric plot, as well as 3-D, differential equation, and bar plot.

The 50g’s large, high-contrast display with adjustable font type and size clearly shows every important part of a formula, calculation, or graph so you’ll be able to clearly read and analyze your results. In addition, you can isolate and evaluate sub-expressions using the intelligent editor, while also cutting, pasting and copying objects as needed. Finally, the large equation library and over 2,300 built-in functions make this calculator ideal for both professionals and students.

50g Graphing Calculator, 12-Digit Pixel Display

Very powerful calculator. Dizzyingly powerful. Excellent display. Positive click buttons. If you’re doing basic algebra, trig, logs, it is very easy to use. I find that when doing more advanced functions, I’m always needing to reference something in the manual to get it done. Sometimes hard to find functions on the keypad, since there are as many as 4 labels per key. SD card works well, but causes about a 2 second delay every time you turn on the calculator, which can be a nuisance when you’re in a hurry. I like the very large RPN stack capability, as well as controllable font, where you can show more than just the 6 lines of the stack that it defaults to. Would recommend the 50g to anyone needing a lot of power. I’ve really only used the 50g in RPN mode, but it will do AOS also.
