Fourier series for a quadratic function Determine the coefficients c0, c1, and c2 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 (,×). Page 14-6
