C4 Mark Scheme Help!

darshan1994

Ok so look at this answer from the existing mark scheme

The answer I got is
-sin(2t)sin^2(t)

I have checked this answer by subing some values and its correct. But the other answer is completely different. I know you can get the same answer by rearranging and using trig identities but atm my answer + method is completely different but equivalent. Would I still get marks? (Would the teacher marking this recognize that this is the same answer rewritten?)

Your answer is equivalent and you would get the marks.
