I am trying to find coefficient of an exponent term in an expression. For example, consider
in: tt = E^(I T0 ( \[Sigma] + Subscript[\[Omega], 1]))
Doing
in: Coefficient[tt, E^(
I T0 (\[Sigma] + Subscript[\[Omega], 1]))]
out: 1
gives 1. However,
in: Coefficient[tt, E^(I T0 \[Sigma])]
out: 0
this returns 0. How do I obtain e^{i*T0*\sigma} as output instead of 0?
I thought PowerExpand will work, but it also did not. I couldn’t find the command to expand exponents
