I have an expression Cos[a t - b]. However when I input it to Mathematica, it automatically converted to Cos[b - a t].
Similarly, Sin[a t - b] would become -Sin[b - a t].
I understand they are equivalent, but for displaying purpose, I would like to have the format of Cos[a t - b] and Sin[a t - b]. Is there any way to do that?
Thank you very much
