Fourier series for a quadratic function
Determine the coefficients c
0
, c
1
, and c
2
for the function g(t) = (t-1)
2
+(t-1),
with period T = 2.
Using the calculator in ALG mode, first we define functions f(t) and g(t):
Next, we move to the CASDIR sub-directory under HOME to change the
value of variable PERIOD, e.g.,
„(hold) §`J@)CASDI`2K@PERIOD `
Return to the sub-directory where you defined functions f and g, and
calculate the coefficients. Set CAS to Complex mode (see chapter 2)
before trying the exercises. Function COLLECT is available in the ALG
menu (
‚×).
