HP 49G scientific graphing calculator

The HP 49g performs in science and math like no other calculator.

HP put the power of 3-D graphing, notes, and lists in an RPN-capable graphing calculator. The HP 49g is a Scientific Programmable Graphing Calculator for professionals in math, science and engineering.

1.5MB of memory (512KB RAM and 1MB Flash ROM for data storage) lets you take full advantage of the biggest, most comprehensive library of third-party calculator programs, games and software applications available for use with a calculator.

The HP 49g’s advanced built-in Computer Algebra System (CAS) puts truly dynamic symbolic manipulation, and symbolic and numeric solving within your grasp. Whether you want to perform complex arithmetic, calculus functions, or solve a system of linear equations, the advanced built-in CAS is flexible, dynamic, and yet completely user-friendly. The HP 49g even prompts you automatically to switch to complex mode when you begin working with complex equations or expressions.
In a text or exam, the answer is only part of the solution; if you’re interested in learning how to get the right answer, the 49g can show you. The CAS step-by-step mode for dynamic derivation, integration and linear algebra problem solving displays all steps and results in textbook mode so you can see and understand the process of problem-solving.

The 49g lets you choose from three input modes according to your preference: familiar textbook, traditional algebraic or efficient RPN. Two default-screen history display options are available: textbook or algebraic.

Edit expressions, text, graphs and programs quickly and easily. More than just a passive editor, this feature of the 49g lets you isolate and evaluate sub-expressions as well as cut, paste, and copy objects, just as you would on your computer. Unsure how to enter an equation or expression correctly? The intelligent editor inserts missing parentheses for you and prompts your next input, both in real-time.
