A=12 B=12 C=7 D=7

A building (or machine) is shaken by a periodic force f(t) defined bye -C, -<t<- -- f(t) = 3C, st< - 20 20 -C; 20 st< (a) (1) Insert YOUR parameter value C for YOUR force f(t). (ii) State the period of f(t). 2n (iii) Sketch f(t) over the domain <t< (iv) State with reason(s) whether the function is odd, even, or neither. (v) Determine the first four non-zero coefficients in the Fourier series for f(t). (b) Write down the first four non-zero coefficients in the Fourier series for g(t) = f(t) – C.-
