Outrageous 2D/3D function and parametric, and 2D polar graphing. It's extreme graphing. An advanced, comprehensive graphing calculator that plots regular 2D/3D functions, 2D/3D parametric relations, and 2D polar functions. Includes all plot modes and graphing calculation features of the TI-83. Graphing Features: -Fast 2D/3D graphing (OpenGL) -Zero, Maximum, Minimum, Intersect (2D function graphs) -Calculus: Derivatives (dy/dx,dy/dt,dx/dt,dr/d), Tangent lines (2D), Integrals (2D) -Adjustable Window settings, colors (3D graphing modes) -Inertial touch panning/scrolling -3D Function/Parametric relation tracing -3D Solid/Wireframe view, Lighting, Augmented reality -Probability distribution -Tables (auto/manual) -Graphing of probability distribution functions (PDFs) -Random colors (2D graphing modes) -Graphing of deriv() and integ() functions (numerical derivative and integration) Calculator Features: -RPN and infix scientific calculators -References to user-defined functions -Complex (imaginary) numbers (a+bi or polar form) -Probability distribution functions (binomial, chi-square, Gaussian (normal), geometric, inverse Gaussian, Poisson, Student-T PDF) -Cumulative PDFs (CDF) -Numbers stored internally as fractions (in calculator and now graphing) -Mixed/improper fraction display -Function integrals, numerical derivatives, roots (zero), extrema -Live calculation: evaluate expressions as they are entered -Trigonometric functions for complex numbers -nCr and nPr (Combinations and permutations) -Degrees, radians, or gradians -Haptic feedback -Unlimited expression history -Physical and chemical constants -User-defined variables RPN Calculator Features: -Unlimited stack depth -Copy and swap features -Single-variable statistics (mean, deviation, etc.) NOTES: -It is preferable to use the Nth-root function instead of fractional powers for greater accuracy (when graphing). -Odd-numbered roots with real solutions are evaluated as a real number (e.g.: (-8)^(1/3) = -2), unlike several Android graphing calculators, as well as Wolfram. -Decimals up to 5 decimal places are converted to internal fractions (even in graphing mode when internal fractions are enabled). -It is not necessary to use the graphing calculator to find roots, integrate, etc. These functions are also available in the infix scientific calculator. -Graphing window may only be square at the moment. -Integration graphing (graphs that use the integ() function) may take a long time. To accelerate graphing of these functions, you may want to decrease the resolution. KNOWN ISSUES (GRAPHING): -When graphing functions with fractional powers, tangent line is reversed for negative x-values. -When graphing at highest resolution or when graphing complicated functions, your phone may run out of memory and cause the calculator to quit. You may try decreasing the resolution for graphs. -Graphing may have hardware-specific issues with some devices. Please report any issues found.
