3. The outcome of this process, illustrated for f(r) = cos(z), is to produce polynomials T "(r) in powers of r-a and a Taylor series Σ..a (z α)" where we have developed a precise fola for the a's in terms of the appropriate derivatives of f(z) evaluated at α. Write out that generic formaula for the α, . based on your work above. (Note: when α-+0, we often just use the simpler notation Pn(r) instead of T:nalr). and call the...
l. (Taylor Polynonial for cos(ar)) Fr f(z) = cos(ar) do the following. (a) Find the Taylor polynomials T.(r) about O for f(x) for n 1,2,3,4,5 (b) Based on the pattern in part (a), if n is an even number what is the relation between T(r) and TR+1(r)? (c) You might want to approximate cs(ar) for all x in。Ś π/2 by a Taylor polynomial about 0. Use the Taylor polynomial of order 3 to approximate f(0.25) when a-2, i.e. f(x)-cos(2x). d)...
(a) Approximate the function f(x) = cos(z) using the first three non-zero terms of its Taylor series centered at a = 0. The potential energy of a spring system can be written as U (t) = KA2 cosa(wt), where t is time, w is the frequency of the spring, A is the amplitude and k is the spring constant. Use the Taylor approximation you obtained to show that near the beginning of the spring's trajectory, the potential energy can be...

(1) Consider the function f(1) =(+ ) cos(2) (a) (4 points) Find the Taylor series for f (at a = 0). You may use without explana- tion the Taylor series for cos(1). (You should write enough to convince us that you know how to write out all the terms without further calculation.) (b) (8 points) Use the Taylor series to find f(100)(O), f(101) (0), and f(102) (0).
1. Taylor series are special power series that are defined from a function f(z) atz = a by fitting higher and higher degree polynomials T, a(x) to the curve at the point (a, f(a)), with the goal of getting a better and better fit as we not only let the degree grow larger, but take a series whose partial sums are these so-called Taylor polynomials Tm,a(x) We will explore how this is done by determine the Taylor series of f(z)...
