PROOF OF TAYLOR’S THEOREM

ection on the proof(s) of Taylor’s theorem. First we recall the (derivative form) of the theorem: Theorem 1 (Taylor’s theorem). Suppose f: (a;b) !R is a function on (a;b), where a;b 2R with a < b. Assume that for some positive integer n, f is n-times di erentiable on the open interval

Baire category theorem is proved and, as an application, it is shown that continuous, nowhere di erentiable functions form a set of second category in the space of continuous functions. 3.1 Spaces of Continuous Functions We studied continuous functions on an interval in MATH2050/60 and in a domain bounded

1 Derivatives of Piecewise Defined Functions For piecewise defined functions, we often have to be very careful in com-puting the derivatives. The di↵erentiation rules (product, quotient, chain rules) can only be applied if the function is defined by ONE formula in a neighborhood of the point where we evaluate the derivative. If we want

examine the di erentiability of j at 0 using de niton. Indeed, using the fact the cosine function is even, lim h!0 cosjhj cos0 h 0 = lim h!0 cosh 1 h = 0; from which we conclude that jis also di erentiable at x= 0. Hence jis di erentiable everywhere. A shortcut is to realize that the cosine is an even function, so j(x) = cosxis dif-ferentiable ...

Chapter 4 Inverse Function Theorem

Indeed, in MATH2060 we learned that if f is continuously di erentiable on (a;b) with non-vanishing f0, it is either strictly increasing or decreasing so that its global inverse exists and is again continuously di erentiable. Example 4.3. Consider the map F: R2!R2 given by F(x;y) = (x2;y). Its Jacobian matrix is singular at (0;0).

The central and un nished task of asset pricing theory is to understand and measure the sources of aggregate risk that drive asset prices.
