Multifunction, dual-screen graphing calculator features a large 21-character by eight-line display with dual-screen capability. On-screen, icon-driven menu. Function keys to select from on-screen menus. Fraction entry and calculation. You can create tables of values from given functions, and generate plots and graphs. Draws and analyzes standard conic sections (Ellipses, Circles, Hyperbolas, and Parabolas). Calculator connects to PC, another FX-9750, or Casio EA-200 Data Analyzer. Graphic and numerical solver key provides instant solutions for root, maximum, Y-intercept, and intersect for any graph. Also has list-based statistics with up to 36 lists and has complex number calculations. Ideal for Pre-Algebra through Calculus and Biology. Allowed on all major exams like SAT and ACT.
Is it possible to have it all–brains, beauty, and brawn? Hewlett-Packard certainly thinks so, and its HP 49G graphing calculator is its shining example.
There’s no getting around the cool styling of the 49G: complete with a sleek metallic blue exterior and a groovy translucent blue hard slide cover, the 49G commands attention. When we were using it in public, it received plenty of looks and inquiries.
But how does it measure up in terms of power? Competing with the notorious Texas Instruments TI89 advanced graphing calculator is tough business, but HP pulls it off with some success. This graphing calculator has all the bells and whistles, including a whopping 1.5 MB of user memory; 2 MB of flash ROM, which enables future software upgrades; a built-in Computer Algebra System (CAS); math, scientific, statistical, financial, and 2-D/3-D graphing capabilities; programming capabilities with reverse Polish notation, assembly, and HP Basic languages; and a unit-to-unit and PC/Macintosh connectivity feature. It also features an equation solver, vectors, lists, arrays, matrices, expressions, and object storing.
One key feature we liked is the history screen, which displays what you’ve already input, so you can reference it to determine what went wrong and correct it. Another notable function is the 49G’s alarm function. You can set the date and time on the calculator, and program the alarm along with a text message to remind you of appointments. You can also set control alarms, which perform functions such as automatically running a program when you’re not using the calculator. Additionally, the calculator emits beeps when you enter an incorrect function, which can be annoying at times–especially when you’re already frustrated.
One of this calculator’s flaws is that it is hard to read the second and third functions above each key. In keeping with the calculator’s sense of aesthetics, the print is in blue and red, which is difficult to see, especially in low lighting situations. It also has a one-touch X-variable key, but no Y- or Z-variable keys.
We wished the manual had gone into greater depth and provided clearer examples, but this might be a concern only to those who don’t immediately get the full functionality of the 49G. Unlike some manuals we’ve seen, the 49G does not show both the necessary keys needed to input an equation along with how they appear on the screen. We also would have liked for the manual to include more examples.
If style is just as important to you as functionality, the 49G is the coolest looking calculator we’ve seen. But if it’s pure power you’re looking for, you’ll probably be just as pleased with any one of the 3-D graphing calculators currently on the market.
