The i41CX+ RPN Calculator with Printer looks and functions just like the graphing calculators that are standard in high school classrooms today, such as the TI-83+ or HP-41C. The interface captures the nostalgia of learning to use a scientific calculator, but only after you take some time to figure out how this app actually works.
If graphing functionality is all you need, then this free app is
worth the download. The graphing calculator plots and traces several
equations at a time, supports a plethora of essential equations
functions, and can email an image of the graph. The X and Y coordinates
are displayed at the top, while pinching the screen zooms in and out of
the graph, enabling you to take a closer look at the coordinates.
Grafly is a sensationally vibrant way to graph your equation. This app
displays your equation in 2D or 3D with full shading, lighting, and
distinction between the inside and the outside of the shape. The 3D
graphs are touch-based, tilt-based, and gravity-based; pinch to zoom in
and out, calibrate “down” for tilt mode, or, in gravity mode, spin the
axis anyway you like by moving your device to get a full, 360 degree
This graphing calculator application has an easy to use interface with
its sizeable buttons, customizable background colors, and clear grid
lines. However, it can be overwhelming at first, since there’s no
tutorial or built-in help available.
This photography calculator is a must for nearly any DSLR shooter. Advanced photographers will use depth-of-field, solar, and flash details. But even beginners can develop skills with the extensive reference material.
