2.4.2. 反函数定理( Inverse Function Theorem)。 给定一个微分同胚( diffeomorphism) \Phi : M \rightarrow N ,必然有 {\Phi }_{ * } 是可逆的( invertible)。一个自然而然的问题是,如果我们知道 {\Phi }_{ * } 是可逆的,我们能否得出 \Phi 是微分同胚( diffeomorphism)的结论?

The Inverse Function Rule (1) Differentiate both sides of the general equation x = g[f[x]] and thus use the Chain Rule to explain symbolically that if y = f[x] and x = g[y] have the same graphs and if both derivatives f′[x] and g'[y] are nonzero, then g′[y]=dxdy=1/...
For, when the inverse is di?erentiable, we may apply this chain rule to di?erentiate the relation F ?1(F (x)) = x to obtain DF ?1(q0) DF (p0) = I , q0 = F (p0), 4 CHAPTER 4. INVERSE FUNCTION THEOREM where I is the identity map. We conclude that DF ?1(q0) = ...
Rule: Horizontal Line Test A function ff is one-to-one if and only if every horizontal line intersects the graph of ff no more than once. Figure 2. (a) The function f(x)=x2f(x)=x2 is not one-to-one because it fails the horizontal line test. (b) The function f(x)=x3f(x)...

The following rule applies in this case – A function f has an inverse if and only if when its graph is reflected about the line y = x, the result is the graph of a function.The following test is used to determine whether the function has an inverse or not. ...
