First-Order Partial Derivatives - Active Calculus
https://activecalculus.org/multi/S-10-2-First-Order-Partial-Derivatives.htmlThe first-order partial derivatives of f with respect to x and y at a point ( a, b) are, respectively, and f x ( a, b) = lim h → 0 f ( a + h, b) − f ( a, b) h, and f y ( a, b) = lim h → 0 f ( a, b + h) − f ( a, b) h, provided the limits exist. 🔗. Activity 10.2.2. Consider the function f defined by. f ( …

Before doing so, we need to define a few terms.
