Answer: In each of 1 through 5, graph the function, the fifth partial sum of its Fourier
Chapter 13, Problem 13.60(choose chapter or problem)
In each of 1 through 5, graph the function, the fifth partial sum of its Fourier series on the interval, and the fifth Cesro sum, using the same set of axes. Repeat this process for the tenth and twenty-fifth partial sums. Notice in particular the graphs at points of discontinuity of the function, where the Gibbs phenomenon appears f (t) = 0 for 3 t < 0 cos(t) for 0 t < 3
