Hope this helped, if not, message me and I'll try to explain further.
200 divided by 54 times 15 times 6 equals 333.3333
The quickest way to get the series is if you already know the series for sine:
Then just multiply the series by 
to get
The first four nonzero terms are simply the first four terms:
