  note that its component in the i direction is the partial derivative of f with respect to x. This is the rate of change of f in the x direction since y and z are kept constant. In general, the component of ∇f in any direction is the rate of change of f in that direction. Example 2 Consider the scalar field f(x,y) = 3x + 3 in two dimen-sions.

  Definition 2. The exp function E(x) = ex is the inverse of the log function L(x) = lnx: L E(x) = lnex = x, ∀x. Properties • lnx is the inverse of ex: ∀x > 0, E L = elnx = x. • ∀x > 0, y = lnx ⇔ ey = x. • graph(ex) is the reflection of graph(lnx) by line y = x. • range(E) = domain(L) = (0,∞), domain(E) = range(L) = (−∞,∞).

For instance, we can use it to conclude that the derivative of x3 +x 2is 3x +2x because we already know the derivative of x3 is 3x2 and the derivative of x2 is 2x. The di erence rule.

The proofs of these differentiation formulas follow immediately from the definitions of the hyperbolic functions as simple combinations of exponential functions. For example, d dx (sinhx)= d dx (1 2 (e x −e−x)) = 1 2 ( e x + −x)=coshx. The remaining proofs are left to Exercises 91–92.

Theorem 3.3.1 If f and g are di erentiable then f(g(x)) is di erentiable with derivative given by the formula d dx f(g(x)) = f 0(g(x)) g (x): This result is known as the chain rule.
