Graphing Calculator turns your phone or iPod into an intuitive high-resolution function plotter and scientific calculator. Features include the following:
- Includes a powerful, yet easy to use scientific calculator.
- Quickly plot and trace multiple equations on the same graph.
- Custom keyboard to speed up entering in equations.
- Pinch to zoom and drag/slide for scrolling the graph in real time.
- The graph view supports portrait and landscape modes.
- Take screen shots, and e-mail graphs to yourself.
- Evaluate your graphs at any x value using the calculator screen.
- Find the exact (x,y) coordinates for roots, intersections, minimums and maximums using the trace mode.
- Supports graphing polar and parametric equations.
- Retina display and multitasking support
- Display the graph on a TV, projector, or external monitor using Apple's VGA adapter (iPhone 4, 4th gen iPod, and iPad only)
- Currently supports the following functions: log, log2, log10, ln, exp, sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, asinh, acosh, atanh, csc, sec, cot, gamma, lgamma, nCr, nPr, min, max, degrees to radians, radians to degrees, absolute value, square root, ceiling, floor, and mod.
Please visit the website for more details and screen shots. Feel free to e-mail me if you have questions, problems, or feature requests.
This version just fixes bugs introduced in the last update. It also has an improved algorithm for finding roots and intersections.
In case you missed the previous update, here are the list of features introduced in 1.3.0:
- Added the ability to graph inequalities.
- Added conditional statements that allow restrictixng the domain and graphing piece-wise functions.
- Relocated the 'x' button, and made it blue. Many people were having problems finding it in the previous version.
- Modified the calculator history so that both the input and the answer can be recalled, depending on which half of the screen is touched.
- Created new functions for calculating the greatest common divisor and least common multiple.
- Added nroot(), which allows you to calculate the nth root of x without having to use the power function.
- Added logbase() for calculating the log of any base.
- Added the atan2(x,y) function.
As always, I would like to thank everyone that emailed me with bug reports.
