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.
NATURE. The Swiss Alps are high, snow-covered mountains most of which are over 13,000 feet (4,000 meters). The most famous peak is the Matterhorn which is 14,692 feet (4,478 meters) tall, but the highest peak is Dufourspitze at 15,203 feet (4,634 meters). Scientists are concerned that glaciers in the Swiss Alps have lost a lot of ice coverage in the past 40 years. This may be related to global climate change.
