Adjustable Range: Control X and Y axis ranges
Interactive Graph: Hover to see coordinates
Color Selection: Choose your line color
Export: Download graphs as PNG images
Examples: Quick access to common functions

Supported Functions

Basic Operations: +, -, *, /, ^ (power)
Trigonometric: sin(x), cos(x), tan(x)
Exponential/Log: exp(x), log(x) (natural log)
Other: sqrt(x), abs(x), floor(x), ceil(x)
Constants: Use Math.PI for π, Math.E for e

Function Syntax Examples

2*x + 3 - Linear function
x^2 - 4*x + 3 - Quadratic
sin(2*x) - Sine with frequency 2
exp(-x^2) - Gaussian curve
x^3 - 3*x^2 + 2*x - Polynomial

Tip: Hover over the graph to see exact coordinates. Use the examples to explore different function types!
