--------------------

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.
- Provides conditional statements allow the user to restrict the domain and graph piece-wise functions.
- Supports graphing polar and parametric equations.
- Supports graphing inequalities, and implicit equations in the form f(x,y)=g(x,y).
- Retina display and multitasking support
- Display the graph on a TV, projector, or external monitor using Apple's VGA adapter (iPhone 4S, iPhone 4, 4th gen iPod, and iPad only)
- Currently supports the following functions: abs, acos, acosh, acot, acoth, acsc, acsch, asec, asech, asin, asinh, atan, atan2, atanh, ceil, cos, cosh, cot, coth, csc, csch, deg2rad, exp, fact, floor, gamma, gcd, lcm, lgamma, ln, log2, log10, logbase, max, min, mod, nCr, nPr, nroot, rad2deg, rand, sec, sech, sin, sinh, sqrt, tan, tanh.

Good, but graphs are sometimes buggy

I generally like this app quite a bit. Most of the time, it's excellent for graphing an equation.

Unfortunately, sometimes it demonstrates significant bugs when graphing the equation. For example, if it doesn't understand the equation, it will just draw a straight line -- rather than telling you that it can't interpret the equation.

As another example, sometimes it draws graphs that are simply wrong. For example, with the equation "y = (1 + x)^(1/9)", it fails to display half of the equation -- the portion to the left of negative one.

Problems like this mean that you can't entirely trust the results of the graphed equations. I've attempted to report some of these bugs to the developer using the provided email address. Unfortunately, he hasn't responded.

Student

This app has been a godsend in helping me get through my college algebra class. In fact, it was mentioned in my textbook and that's why I bought it. It sure beats buying an expensive graphing calculator like I did back in high school, and it functions just as well. I highly recommend this app.

Great App but NEEDS CALCULUS

This app is absolutely wonderful and I use it almost every day on all of my iOS devices, however it NEEDS Calculus functions. I'm a Mechanical Engineering major in college starting this Fall and the ability to graph derivatives, integrals, and possibly even vector/slope fields would be much appreciated.
