the question is find a function, f, and a value, a, such that:
2 times the integral from a to x of f(t)dt = 2sinx - 1
(sorry i don't know how to make it look nice)
well the first thing i did was divide by 2, then take the derivative of each side:
f(x) - f(a) = cos x
and now I am stuck. am i correct so far? where do i go from here? thanks.
