Graphing Calculator

Time Magazine selected "Graphing Calculator" as one of the top 10 back-to-school iPhone applications.

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. 
• Supports graphing implicit equations equations in the form f(x,y)=g(x,y), which makes it possible to graph equations that cannot explicitly be solved for y in terms of x.
• Supports graphing inequalities.
• Provides conditional statements allow the user to restrict the domain and graph piece-wise functions.
• 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: 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.
