Chapter 16, Problem 16.14(choose chapter or problem)
The periodic function shown in Fig. P16.14 is even and has both half-wave and quarter-wave symmetry.
a) Sketch one full cycle of the function over the interval \(-T / 4 \leq t \leq 3 T / 4\).
b) Derive the expression for the Fourier coefficients \(a_{v}, a_{k}\), and \(b_{k}\).
c) Write the first three nonzero terms in the Fourier expansion of f(t).
d) Use the first three nonzero terms to estimate f(T/8).
