Equation Visualizer

Overview

Equation Visualizer is a Streamlit-based web application that allows users to input mathematical expressions, convert them into valid SymPy expressions using Gemini AI, and plot their graphs.

Features

• Accepts mathematical expressions with x as the only variable.
• Uses Google Gemini AI to correct and convert input expressions into SymPy-compatible format.
• Plots the function using Matplotlib.
• Handles errors such as undefined variables, division by zero, and invalid syntax.

Requirements

Ensure you have the following installed:

• Python 3.8+
• Required Python libraries:

  pip install streamlit sympy numpy matplotlib google-generativeai python-dotenv

• A valid Google API key stored in a .env file:

  echo "API_KEY=your_google_api_key_here" > .env

Usage

1. Clone the repository:

   git clone https://github.com/A-Vamshi/EquationVisualizer.git
   cd EquationVisualizer

2. Install dependencies:

   pip install -r requirements.txt

3. Run the application:

   streamlit run app.py

4. Enter a mathematical expression in the input box and click "Graph the equation."

Example Inputs & Outputs

Input Expression	Converted SymPy Expression
x^2 + 3*x + 2	x**2 + 3*x + 2
sin(x) + cos(x)	-1 (invalid input)
5x^2 + 2x + 3	5*x**2 + 2*x + 3
