not exactly sure what the question is...

couple of points though, it is usually easier to use a different dummy variable when you use a subtitution

say you have
[tex] \int_b^a dt f(t) [/tex]

and want to change to u(t) = t/2, then
t=2u
dt = 2.du
u(a) = a/2
u(b) = b/2

so the integral becomes
[tex] \int_{b/2}^{a/2} 2.du f(2u) [/tex]

see how this compares with your case...
