An alternating current generator produces a voltage modeled by a periodic square wave of period T=2T = 2 seconds, defined as V(t)=110V(t) = 110 V for 0<t<10 < t < 1, and V(t)=110V(t) = -110 V for 1<t<21 < t < 2. What is the amplitude of the fundamental frequency component (the n=1n=1 term in the Fourier series expansion of form ancos(npit)+bnsin(npit)a_n \\cos(n \\pi t) + b_n \\sin(n \\pi t))?
