Problem 13.36

Let f and f be piecewise continuous on [L, L]. Use Bessels inequality to show that lim n L L f (x) cos nx L dx = lim n L L f (x)sin nx L dx = 0. This result is called Riemanns lemma.

Step-by-Step Solution:
Step 1 of 3

1.2 Finding limits Graphically To find the limit graphically of a function you have to follow the function from both the positive side and from the negative side of the coordinate system towards the number x approaches. For example, For this function as x approaches -2, if you follow the function from both sides the limit equals 4. 1.3 Finding limits...
