The partial derivative of a function f (x, y, ...) with respect to the variable x is variously denoted by.Since in general a partial derivative is a function of the same arguments as was the original function, this functional dependence is sometimes explicitly included in the notation, as in.he cross partial derivative with respect to x and y is obtained by taking the partial derivative of f with respect to x, and then taking the partial derivative of the result with respect to y, to obtain.
Considering mountains with a topographic prominence of at least 300 m (980 ft), the Matterhorn is the sixth-highest summit in the Alps and Europe outside the Caucasus Mountains.
