Next, we move to the CASDIR sub-directory under HOME to change the value
of variable PERIOD, e.g., „ (hold) §`J @) C ASDI `2 K @PERIOD
`
Return to the sub-directory where you defined functions f and g, and calculate
the coefficients (Accept change to Complex mode when requested):
Thus, c

The Fourier series with three elements will be written as
g(t) Re[(1/3) + ( i+2)/
A plot of the shifted function g(t) and the Fourier series fitting follows:
