Ddx dxdy ⋅ddy dydx is equal to

WebMar 8, 2009 · ddx and ddy are "operators", in the mathematical sense of the word, in that they operate on functions rather than numbers. They determine how the function (read: expression) changes over space. I think a few examples would be instructive. ddx (3): would evaluate to 0 everywhere. 3 is 3. It doesn't change at different pixels. WebMay 2, 2015 · The symbol. d y d x. means the derivative of y with respect to x. If y = f ( x) is a function of x, then the symbol is defined as. d y d x = lim h → 0 f ( x + h) − f ( x) h. and this is is (again) called the derivative of y or the derivative of f. Note that it again is a function of x in this case. Note that we do not here define this as d ...
