Question

given the function f(r,teta,phi) and the relations x=rsin(teta)cos(phi), y=rsin(teta)sin(phi) and z=rcos(teta). find the partial derivative df/dy

Answer 1

shut up noob

Answer 2

String objects are a special type of container, specifically designed to operate with sequences of characters.

Unlike traditional c-strings, which are mere sequences of characters in a memory array, C++ string objects belong to a class with many built-in features to operate with strings in a more intuitive way and with some additional useful features common to C++ containers.

Answer 3

z = f(r,teta, phi) ?

Answer 4

z=rcos(teta)
