C++ Mathematical Equation Interpreter & Visualizer

A GUI application built with Qt/C++ that parses complex mathematical equations, generates parse trees, and visualizes graphs with customizable bounds. Ideal for educational purposes and mathematical exploration.

Features

• Equation Parsing & Validation
  Supports complex equations with operators (+, -, *, /, ^), functions (sin, cos, log, etc.), and variables
• Interactive Parse Tree Visualization
  Auto-generates syntax trees for equations to demonstrate parsing logic
• Graph Plotting
  Renders 2D graphs with adjustable domain (min/max X values)
• Error Highlighting
  Identifies syntax errors and invalid expressions in real-time
• Variable Support
  Allows single-variable equations (e.g., f(x) = 2x^2 + 3)
• Export Capabilities
  Save graphs and parse trees as PNG/SVG
• Cross-Platform
  Works on Windows, Linux, and macOS

Installation

Requirements
