f(x) = cos^2(x) + cos(x)
M = maximum of f(x)
m = minimum of f(x)
a = M - m = ?

Excellent, many thanks! Seriously? Learn to differentiate.
I can't say I've had much previous experience with differentiation of any kind. And by that I mean none at all. ;_; But I now understand this one, so thanks!
Are you (or anyone) up for a second one?
f:R->R
f(x)= sin^2x - x^2 + (x^4)/3
f(n+1)(x) = ? (That is, f differentiated or derived (whichever is correct in English) n+1 times.) where n>=4.
