I think I'll pass on this and your others. There seems to be a lack of completeness of the information provided.

Man, can you cut the TEX? I think you have ∫[0,3π/2] x^2 cosx dx = a - bπ^2/c well, that's 2 - 9/4 π^2, so (a,b,c) = (2,9,4), so a+b+c=15

dq/dt is rate of q changing with respect to time. It is a calulus term. dx/dt is rate of change of x, and so on. That is what surprised me about the question, rate is a calculus term.
