A Python Scientific and Graphing Calculator for Integrals and Derivatives
PyCalculus is a fast, intuitive, and user-friendly Python-based scientific calculator that specializes in calculus operations — particularly derivatives and integrals. Built using Tkinter for the GUI, NumPy for numerical computations, and Matplotlib for real-time graphing, PyCalculus offers a powerful visual and computational tool for students, educators, and math enthusiasts.
- 🔢 Symbolic and Numerical Calculations
- Calculate derivatives (first and higher-order)
- Evaluate indefinite and definite integrals
- 📊 Graphing Capabilities
- Visualize functions, derivatives, and area under the curve (integrals)
- Toggle between function views and calculus visualizations seamlessly
- ⚡ Performance-Oriented
- Utilizes optimized numerical libraries like NumPy for fast and reliable computation
- 🖥️ Intuitive GUI
- Clean and responsive interface built with Tkinter
- Easy input and interactive graph plotting with minimal setup
git clone https://github.com/cjohnramirez/PyCalculus.git
cd pycalculus
pip install -r requirements.txt
python main.py- Python 3.8+
- NumPy
- Matplotlib
- Tkinter (usually bundled with Python)
- Calculate:
d/dx (x^2 + 3x)→ shows symbolic and numeric output∫ x^2 dx→ plots area under curve, provides indefinite integral∫₀¹ x^2 dx→ computes and displays definite integral result and shaded region on graph
- Visualize:
- Area under the curve
- Multiple derivatives
- Infinite integrals
PyCalculus is designed to help:
- Learn how derivatives and integrals work through visual feedback
- Understand calculus concepts beyond just numbers
- Serve as a teaching tool in classrooms or tutoring sessions
- Support for multivariable functions
- Export graphs as images
- History and session saving
- Light/dark mode for the GUI
