Abdullah Graph Equation

A Python package for graphing mathematical equations from string input.

Installation

pip install abdullah_graph_eq

Usage

from abdullah_graph_eq import graph_equation

# Graph a simple quadratic equation
graph_equation("x**2 + 2*x + 1")

# Graph a trigonometric function
graph_equation("sin(x)")

# Graph with custom range
graph_equation("x**3 - 2*x**2 + x - 1", x_range=(-5, 5))

# Save the plot
graph_equation("cos(x) + sin(2*x)", save_path="my_graph.png")
