• Machine Learning: Gradient descent, backpropagation, optimization
• Computer Graphics: Curves, surfaces, animation, physics simulation
• Algorithm Analysis: Growth rates, complexity analysis
• Signal Processing: Fourier transforms, filtering
• Optimization: Finding optimal solutions in algorithms
• Physics Simulation: Game engines, robotics
