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 Balmhorn is a large peak located above LÃ¶tschenpass and Gemmipass in the western Bernese Alps. The peak supports a large glacier on its north side. The eastern and northeastern aspects are rock. To the southeast, it is connected to the Rinderhorn by long snow and rock ridge (Zackengrat). To the west, it is connected to Altels by an elegant narrow ridge. Jakob and Melchior Anderegg with Frank, Horace, and Lucy Walker made the first ascent of the Balmhorn via the Zackengrat on 21 July 1864.
