what is sin 3x*cos2x*cos3x*sin2x

Do you mean sin3x*cos2x + cos3x*sin2x?  If so this simplifies to sin(5x).

As written, the original doesn't simplify much, though it can be written as (sin²5x - sin²x)/4

Try uploading it again in 30 minutes or so.  I've also noticed occasional hiccups with uploading images.
