comment Pertubation series of given equations
Thanks, I would also be interested in a generalisation to more than one variable and more than one function, for example in the case of a system of two coupled equations in f[x,y], g[x,y] where both f and g need to be expanded up to order $n$. Any idea? I can't see how to extend your code in order to work for these cases..

I guess that eq should be expr, right?

And also entered the code that does what I want, but I would like to know if there is a more efficient way to do it, and how to embed all this in a function definition.

I added the desired result, and explained how I usually do it.

comment Dividing out any constant factor from expression
This does not work as I would like it too, i.e., without knowing in advance if my expression has 2 as common divisor.

@DanielLichtblau What if I do not know in principle that 2 will work?

@glS That is true, but I would like to be able to change options and isolate Cos[2 x] instead. It would be great to have also that freedom. But your answer is already very helpful indeed.
