Partial derivatives of parametric surfaces
Since the input is multi-dimensional, you cannot take the ordinary derivative of this function, but you can take a partial derivative. The focus of this article is on getting an intuitive feel for what those partial
Partial derivatives, introduction (video) | Khan Academy
Partial derivatives tell you how a multivariable function changes as you tweak just one of the variables in its input.
Derivatives of multivariable functions | Khan Academy
What does it mean to take the derivative of a function whose input lives in multiple dimensions? What about when its output is a vector? Here we go over many different ways to extend the idea of a
The gradient vector | Multivariable calculus (article)
The gradient stores all the partial derivative information of a multivariable function. But it''s more than a mere storage device, it has several wonderful interpretations and many, many uses.
Second partial derivatives (article) | Khan Academy
A brief overview of second partial derivative, the symmetry of mixed partial derivatives, and higher order partial derivatives.
Introduction to partial derivatives (article) | Khan Academy
The partial derivative is a way to find the slope in either the x or y direction, at the point indicated. By treating the other variable like a constant, the situation seems to simplify to something we can
Multivariable calculus
