Hi,

I am trying to write an expression in terms of Cos, Sin, and Exp, but I don't want Cosh, Sinh.

For example:
Vc = (s + 5)/s/(s^2 + 2 s + 5)
Apart[Vc]
vc = InverseLaplaceTransform[Vc, s, t]
Expand[vc]
FullSimplify[vc]

The final output should come out to something like
1-Exp[-t]*Cos[2t], however I am only getting either Exp with imaginary numbers, or Cosh and Sinh but I believe it can be written with only real numbers.

Thanks for your help
