Definite & Indefinite Integral Calculator

This is a Python-based GUI application for calculating both definite and indefinite integrals using multiple numerical and symbolic methods. The app is built with Tkinter for the GUI and supports several integration techniques like:

• Gauss-Legendre Quadrature (torchquad)

• Monte Carlo Integration (torchquad)

• Scipy's quad method (Use for -inf, inf bounds of the integral)

• SymPy's Symbolic Integration

• Has very precise Gauss-Legendre algorithm that is capable of handling complex definite integral problems

Features

• Calculate definite integrals with custom bounds.
• Calculate symbolic indefinite integrals.
• Supports infinite bounds (-inf, inf).
• User-friendly GUI.
• Safe parsing of mathematical functions.
