HP HP49G Graphing Calculator

The HP49G graphing calculator is an RPN-capable calculator with powerful 3-D graphing, note, and list features. With its advanced built-in Computer Algebra System, you can perform complex arithmetic and calculus functions and solve systems of linear equations, in addition to having dynamic symbolic manipulation and symbolic and numeric solving at your fingertips. You can also make statistical inferences, perform hypothesis tests, and measure confidence intervals that relate to populations. Sample data can be inputted, viewed, and edited in table format (similar to a computer spreadsheet), and then you can plot the results.

The large 1.5 MB memory (512 KB RAM and 1 MB Flash ROM for data storage) encourages taking full advantage of the comprehensive library of third-party calculator programs, games, and software applications. The HP49G doesn't just give you the answer to your equation; it can walk you through the process of finding that answer by using the CAS step-by-step mode for dynamic derivation, integration, and other linear algebra problem-solving techniques. All steps and results are displayed in textbook mode on the 131 x 64 pixel, high-contrast screen. If you aren't fond of textbook mode, try traditional algebraic or RPN input modes.

With its smooth edges, streamlined curves, and light blue metallic exterior, the HP49G is a sleek and modern tool for professionals or students in the sciences, math, and engineering. --Dana Van Nest
