The Fourier series for f(t) = 0 t, 0 f(t + 4) = f(t), 4 sin(m/2) sin -2 <t<-1 -1<t<1 is given by 1<t<2 allt s(t) = Σ. =1 2 cos(m/2) + • Use Dirichlet theorem to determine S(1) = (decimal). • Substitute t = 1 and use the identity 2 sin(a) cos(a) = sin(2a) to determine such A so that 20 sin(an/2) AS(1) (decimal). • The complex Fourier series for f(t) can be written as f(t) ~ Cheimnt/2. Determine co (integer) and icz = (round to the third decimal place). • What can you say about c_2020? Choose one of the following options: A: c_2020 = -C2020,B: C_2020 = C2020, C: c_2020 = C1010, D:c_2020 = (C2020)*. Type the corresponding capital letter =
