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. It is also the fifth-highest summit of both Valais and Switzerland and the third highest summit of both the Aosta Valley and Italy.
The Matterhorn, the king of mountains, is the most-photographed mountain in the world. It is myth and emblem for Alpinists and photographers alike, as well as Switzerlandâs most famous landmark and symbol.ssence of the Matterhorn. Thanks to its shape and its free-standing position, the Matterhorn is considered to be the epitome of a mountain. There is no better-known mountain in the world whose natural shape is so close to a pyramid. 100 million years ago, enormous forces brought Africa closer to Europe.
