## What is GT Graph?

GT Graph transforms your device into a powerful mathematical visualization tool. Plot equations, explore calculus concepts, and bring mathematics to life with stunning interactive graphs.

PLOT ANY EQUATION
- Cartesian functions
- Polar curves
- Parametric equations
- Implicit equations
- Inequalities with shaded regions

INTUITIVE INPUT

Type equations naturally with implicit multiplication support. Write 2x instead of 2*x, or 2sin(x) instead of 2*sin(x). GT Graph understands mathematical notation the way you write it.

COMPREHENSIVE FUNCTION LIBRARY
- Trigonometric: sin, cos, tan, sec, csc, cot
- Inverse trigonometric: asin, acos, atan
- Hyperbolic: sinh, cosh, tanh
- Exponential and logarithmic: exp, ln, log, log2
- Power functions: sqrt, cbrt, abs
- Constants: pi, e, phi (golden ratio)

MULTIPLE GRID TYPES
- Standard Cartesian grid
- Trigonometric grid with pi-labeled axes
- Polar coordinate grid with radial lines
- Logarithmic scale grid

CALCULUS TOOLS
- Calculate derivatives at any point
- Compute definite integrals with visual shading
- Find zeros (roots) of functions
- Locate local minima and maxima
- Generate value tables

INTERACTIVE EXPLORATION
- Pinch to zoom, drag to pan
- Tap to show tangent lines
- Crosshair cursor displays coordinates
- Plot multiple equations simultaneously
- Color-coded graphs for easy identification

SAVE AND SHARE
- Save your work as .gtgraph files
- Export and share with colleagues
- Equation history saves your last 25 entries
- Settings persist between sessions

Perfect for:
- Students learning algebra, trigonometry, and calculus
- Teachers creating visual demonstrations
- Engineers and scientists visualizing data
- Anyone curious about mathematical beauty

GT Graph combines the power of professional graphing software with the elegance of modern design. Start plotting today!
