Chain Rule for Derivative — The Theory https://ift.tt/2YDoEwS About 0 Minutes In calculus, Chain Rule is a powerful differentiation rule for handling the derivative of composite functions. While its mechanics appears relatively straight-...
1. 若 n 为任意实数且 u=g(x) 可微,则 ddx(un)=nun−1dudx (或者 ddx[g(x)]n=n[g(x)]n−1⋅g′(x)) 2. ★ 指数函数的导数: ddx(ax)=axlna 证明: ddx(ax)=ddx[(elna)x]=ddx[e(lna)x] =e(lna)x⋅ddx[(lna)x]=e(lna)x⋅lna=axl...

This lesson defines the chain rule. It goes on to explore the chain rule with partial derivatives and integrals of partial derivatives.
Find the first derivative of ff given f(x)=ln(x2+x)f(x)=ln(x2+x) Solution to Example 5 Let u=x2+xu=x2+x and f(u)=lnuf(u)=lnu , hence dudx=2x+1dudx=2x+1 and dfdu=1udfdu=1uUse the chain rule and substitute ...
x . This one fact, plus the chain rule, allows us to differentiate any exponential function. For example, take f(x) = 2 x . Then using the laws of exponential functions, this can also be rewritten f(x) = (e ln 2 ) x = e x ln 2 . This is a composition of two function...
1. Chain Rule Recall that the chain rule for functions of a single variable gives the rule for di?erentiating a composite function: if y = f (x) and x = g(t), where f and g are di?erentiable functions, then y is a a di?erentiable function of t and dy dx dy = . dt ...
