Remember formula (3) as the following statement: the directional derivative of z = f(x,y) in the direction of u equals the x-derivative of f multiplied by the x-component of u, plus the y-derivative of f multiplied by the y-component of u. Proof of Theorem 1: Definition (2) and the Chain Rule from the last section give F0(s) = d ds [f(x0 + u1s ...

The derivative of sin(3x + 2) is not cos x or even cos(3x + 2). The chain rule produces the extra factor 2, which in this case is the number 3. The derbotive of sin(3x + 2) id cos(3x + 2) timed 3. Notice again: Because the sine was evaluated at u (not at x), its derivative is also evaluated at u. We have cos(3x + 2) not cos x

EXAMPLE3.2.1 Find the derivative of f(x) = x5 +5x2. We have to invoke linearity twice here: f′(x) = d dx (x5 + 5x2) = d dx x5 + d dx (5x2) = 5x4 + 5 d dx (x2) = 5x4 +5·2x1 = 5x4 + 10x. Because it is so easy with a little practice, we can usually combine all uses of linearity into a single step. The following example shows an acceptably ...

f(x,y) is defined as the derivative of the function g(x) = f(x,y), where y is considered a constant. It is called partial derivative of f with respect to x. The partial derivative with respect to y is defined similarly. We also use the short hand notation fx(x,y) = ∂ ∂x f(x,y). For iterated derivatives, the notation is similar: for ...
