f=x^2.  It's easy to compute the fouier transform. F(y)=fourier(f,x,y).

However, I want to do more. replace the variable y with a new formula g(z)=z^2.

I tried  "subs(y=g,F)". But failed. Need your help.

with(MTM):

f := x^2

x^2

 (1)

F := fourier(f, x, y)

-2*Pi*Dirac(2, y)

 (2)

g := z^2

z^2

 (3)

subs(y = g, F)

-2*Pi*Dirac(2, y) = z^2

 (4)
