Dear group,

I need  to  implement the following function

trans[pol_]:=If[PolynomialQ[pol,t],PolynomialQuotient[pol,t+t1,t]
(t+t1)+PolynomialRemainder[pol,t+t1,t],pol]

to expressions like Sin[pol] + Cos[pol] + Log[pol]. For example, i want to
get Sin[2t+t1] in the form Sin[2(t+t1)-t1]. 

Can you help me with this, please.

Regards,

Irina
