You already know FS of 푥푥(푡푡) =푐푐푐푐푐푐(푡푡) and 푥푥(푡푡) =푐푐푐푐푐푐(푡푡) + 5. We derived the FS coefficients using direct analysis (e. g., Euler formula). Using the same approach, derive exponential FS coefficients 푎푎푘푘=퐷퐷푛푛 of 푥푥(푡푡)= 1 +푐푐푠푠푠푠(2푡푡)Plot the magnitude and phase of 푎푎푘푘 coefficients (2 plots, examples are in slides FS:42-43). Briefly comment on the differences between sin and cos, and the FS coefficient
