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.
Mountain goats can weigh from 125 to 180 lbs. (57 to 82 kilograms) and grow from 49 to 70 inches (124 to 178 centimeters) long. Their black horns grow up to 8 to 12 inches (20 to 30 cm) long. They do not shed their horns, so a goat's age can be determined by counting the annual growth rings. Both males and female mountain goats have horns, according to the Animal Diversity Web (ADW) at the University of Michigan.
