Using the Action Menu

The Fourier Transform pairs are defined using two arbitrary constants a, b.

F() =		b			 f(t)eibt dt
		(2)1–a
					– 
f(t) =		b		 F()e–ibt d
	(2)1+a
				– 

The values of a and b depend on the scientific discipline, which can be specified by the value of n (optional fourth parameter of Fourier and invFourier) as shown below.
