The plot you see after a successful run is Magnitude Plot;

For Phase plot; plot D3;

I

Spect()

Under this notation in F0 with Xrange of a period or integer multiple of T.

eg. F0 for sin(X) in Xrng 0 to 2*pi or -pi to +pi

eg. 1*Heaviside(X)+-1*Heaviside(X-1) Xrng 0 to 2; this defines PiecewiseFunction of X=1 between 0 and 1; X=0 elsewhere repeating at a T=2;

II

spect(lowerLimit, Period)

Under this notation plot in F0; don't care about Xrng but specify the range in function call.

eg. F0 for sin(X); call function spect(0,2*pi) OR spect(-pi,2*pi); bcos sinX T=2pi always.

the ~Fourier plot can be found under Function app. Press plot under Function App.

eg. 1*Heaviside(X)+-1*Heaviside(X-1); PiecewiseFunction of X=1 between 0 and 1; X=0 elsewhere;

function call spect(0,2) for T=2; check plot on Function App;

complex function:

COS(X)+sin(2X)+COS(3X+.11)+2 at F0

fo(rads/s) for this function is gcd(1,2,3) in exact CAS; hence T=2*pi/gcd(1,2,3)

under I notation

plot F0 for Xrng 0 to T or 0 to integer*T; then Spect();

under II

plot F0 then spect(0,T)
