http://www.columbia.edu/itc/sipa/math/calc_rules_multivar.html WebThe quotient rule of partial derivatives is a technique for calculating the partial derivative of the quotient of two functions. It states that if f (x,y) and g (x,y) are both differentiable functions and g (x,y) is not equal to 0, then: ∂ (f/g)/∂x = (∂f/∂xg - f∂g/∂x)/g^2 ∂ (f/g)/∂y = (∂f/∂yg - f∂g/∂y)/g^2

Here are a couple of the third order partial derivatives of function of two variables. f xyx = (f xy)x = ∂ ∂x ( ∂2f ∂y∂x) = ∂3f ∂x∂y∂x f yxx = (f yx)x = ∂ ∂x ( ∂2f ∂x∂y) = ∂3f ∂x2∂y f x ... WebTo find the critical points of a two variable function, find the partial derivatives of the function with respect to x and y. Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points.

WebIn mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument … WebWhat are derivatives? The derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f (x) f ( x), there are many ways to denote the derivative of f f with respect to x x. The most common ways are df dx d f d x and f ′(x) f ′ ( x).
