Hey guys,
My teacher gave us this revision sheet and am having trouble with this question. Was wondering if u could help me out?? thanksreceived_2587148421307142~2.jpeg
 
Where (>0) does y = c intersect y = 2x-3x^3? If the answer to that is x=D1 and x=D2, then you'll need two integrals, one on [0,D1] and another on [D1,D2]. Where did those values come from?

I dare say c is in [0,(4/9)*sqrt(2)]. You tell me why.

Have you been introduced to the concept of finding the area between two curves?
