Partial Derivative (Definition, Formulas and Examples ...
byjus.com › maths › partial-derivativeSame as ordinary derivatives, partial derivatives follow some rule like product rule, quotient rule, chain rule etc. Product Rule. If u = f(x,y).g(x,y), then, Quotient Rule. If u = f(x,y)/g(x,y), where g(x,y) ≠ 0, then; Power Rule. If u = [f(x,y)] n then, the partial derivative of u with respect to x and y defined as; u x = n|f(x,y)| n-1 ∂f/∂x

We will call g′(a) g ′ ( a) the partial derivative of f (x,y) f ( x, y) with respect to x x at (a,b) ( a, b) and we will denote it in the following way, f x(a,b) = 4ab3 f x ( a, b) = 4 a b 3. Now, let’s do it the other way. We will now hold x x fixed and allow y y to vary.

tutorial.math.lamar.edu › Classes › CalcIIIMay 31, 2018 · The partial derivative f x(a,b) f x ( a, b) is the slope of the trace of f (x,y) f ( x, y) for the plane y = b y = b at the point (a,b) ( a, b). Likewise the partial derivative f y(a,b) f y ( a, b) is the slope of the trace of f (x,y) f ( x, y) for the plane x = a x = a at the point (a,b) ( a, b).
