Partial Derivative
Domain: Math & Logic for AI
🎯 Motivation
The derivative with respect to one variable while keeping others fixed. Used when functions have many inputs.
📋 Concrete Example
For f(x, y) = x*y, partial derivative with respect to x is y (treat y as constant).
🔗 Analogy
Like adjusting only the volume on a mixing desk while leaving all other sliders alone, to see the effect.
