Screenshot Description Graphite is an efficient and accurate graphing calculator for the iPhone and iPod touch. Graphite combines an intuitive, polished multi-touch interface with powerful numeric methods to allow fast and precise computation of roots, extrema, integrals, and intersections. Scale axes independently using the custom pinch gesture, then trace along curves for values using as many fingers as you want! Graphite lets you easily manage as many equations as you need and quickly enter new ones using the dedicated equation input screen. If Graphite's helpful yet unobtrusive usage instructions and error dialog boxes still leave some aspect confusing, it also holds an extensive onboard help document. What new in this version? Fixed a bug where the numeric integrator occasionally did not converge for integrals equaling zero. Fixed a bug where equations' line widths were not retained upon program exit. Fixed a parser bug occurring when an operator of low precedence appears after more than one operator of high precedence. Changed "Done" button in calculation mode to read "Exit" to avoid confusion. Added a clear button to the equation input text field.
