RE : Problem with function


Hello !

If you want your function to be integrable and so on, you have to use UnitStep :

g[t_]:=UnitStep[t,1-t]t+UnitStep[3-t,t-1](1.5-.5t)

In[4]:=
Plot[g[t],{t,-4,4}]


And then, just use "FourierTransform".

But have a look at the Help browser to look what parameters you wish.

Default :	ff[Ï?_] = FourierTransform[g[t], t, Ï?]

How to compute in Mathematica  fourier transform  of function:

            t     ,0=< t =<1
g(t)=
            1.5-0.5t , 1< t =<3

to tell the truth i dont even know how to make Mathematica print that
function.

Regards,
