In 51 and 52 use a CAS to plot graphs of partial sums
Chapter 11, Problem 11.1.97(choose chapter or problem)
In 51 and 52 use a CAS to plot graphs of partial sums {SN(x)} of the given trigonometric series. Experiment with different values of N and graphs on different intervals of the x-axis. Use your graphs to conjecture a closed-form expression for a function f defined for 0 x L that is represented by the series.f(x) 4 n1(1)n 1n2 cos nx
