3. (pp. 592, Marsden & Hoffman] Suppose that f:1-1, 1] → R is differentiable on (–,], f(-1) = f (TT), and f' and f" are sectionally continuous, with jump discontinuities. Show that a L 15()dx = Ž** (% +6%), T J - n=1 where an, bn are the Fourier coefficients of f. Use Schwarz's inequality to show that the number series -1 (a2 + 6%)"/2 converges.

Please write carefully! I just need part a and c done. Thank you. Will rate. 3 This problem is to prove the following in the precise fashion described in class: Let O C R2 be open and let f: 0+ R have continuous partial derivatives of order three. If (ro, o) O a local maximum value at (To, Va) (that is, there exist r > 0 such that B. (reo) O and (a) Multivariable Taylor Polynomial: Suppose that f has...
problem1&2 thx! interval in R is a set IC R such that for all <y < z in R, if E I and z e I then Recall that an points yE I. We call an interval non-degenerate if it contains at least two (1) Let I be a nondegenerate interval in R, and suppose f: IR is continuous (a) Show that f[] is an interval in R. (b) Show that if I is closed and bounded, then so is...
