The more general case can be illustrated by considering a function f(x,y,z) of three variables x, y and z. If y and z are held constant and only x is allowed to vary, the partial derivative of f with respect to x is denoted by ∂f ∂x and deﬁned by ∂f ∂x = lim ∆x→0 f(x+∆x,y,z)−f(x,y,z) ∆x (1) Similarly we deﬁne ∂fOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f (x) = 5x + 1, then the slope is just 5 everywhere, so f' (x) = 5. Then f'' (x) is the slope of a horizontal line--which is 0. So f'' (x) = 0. See if you can guess what the third derivative is, or ... 16 Apr 2021 ...
