simplify this ?2sin(2x+45)

Hi!
I want to simplify this ?2sin(2x+45), but all I can think of is y=?2sin(2x+45)
and make a graph.. In that case, baseline is 0, ?2 is the amplitude, the period is 180, pitch 45 and starting point is -22.5 (I might have that wrong because 45 is in degrees), the maxline is 1.41 and minimum is -1.41.
Is that correct way to do it, or is there another way to simplify it?
I really don't understand the question.

Best regards.

Found the answer.. but it was rather fun to make the graph
Thanx

That's probably the intended answer, but it's debatable whether it's any simpler than the original expression.
