About Good Grapher - scientific graphing calculator
Good Grapher™ - great and very powerful scientific graphing calculator. It will become your reliable assistant from elementary school to university and work.
Customer reviews:
"Amazing app! I love it. It has Many great features that beat my T83"
"Best calculator. It's my favorite app now ) Functionality and usability is on top level."
SCIENTIFIC CALCULATOR:
- History tape
- real and complex numbers
- radians and degrees angle modes, support for minutes, seconds, grads
- constants: astronomical, atomic, electromagnetic, mathematical, physicochemical, universal
- functions: sin, cos, tan, cot, sec, csc, sinh, cosh, tanh, coth, asin, acos, asec, acsc, atan, acot, asinh, acosh, atanh, acoth, log2, log10, ln, logn(n,x) (log x with base n), √, ³√, abs, avg, ceil, floor, round, deg2rad, rad2deg, max, min, sgn, lcm, gcd, nCr, nPr, arg, real, imag, conj, polar
- operators: +, -, *, /, % (modulus), ^, ! (factorial), ' (minutes), " (seconds), {grad}
- ← - assignment operator and A, B,…,J variables for values storage
- copy/email calculations
2D GRAPHING CALCULATOR:
- carefully-designed graph visualization with multi-touch support (pinch to zoom and drag to scroll)
- cartesian y(x) and x(y), polar r(θ) graphs (parametric x(t)y(t) and implicit in Pro version)
- inequalities drawing (in Pro version)
- function tracing and automatic min/max, zeros, intersections scanning for all function types
- intersection discovering between different function types, e.g. between cartesian y=x and polar r=1
- unlimited number of functions can be drawn simultaneously
- standard, trigonometric and logarithmic axes
- proportional and non-proportional scaling
- customizable graph colors
- table of graph values
- copy, save, email screenshot
3D GRAPHING CALCULATOR:
- pinch to zoom and drag to rotate
- cartesian x(y,z), y(x,z), z(x,y), cylindrical x(p,φ), y(p,φ), z(p,φ), spherical r(θ,φ) graphs (parametric xyz(u,v) and implicit in Pro version)
- inequalities drawing (in Pro version)
- points, lines, surface drawing modes
- configurable graph bounds
- copy, save, email screenshot
MATH SOLVER:
- polynomial solver:
2x - 3 = 0 (linear)
3x² + 4x + 8 = 0 (quadratic)
5x³ + 2x² - 4x + 2 = 0 (cubic)
7x⁴ - 2x³ + 3x² + 2x - 1 = 0 (quartic)
- system of linear equations solver
with 2 unknown
2x - 9 = 9
3x + 4y = -13
with 3 unknown
