Calc ll integrals help!!

[From: ] [author: ] [Date: 12-02-02] [Hit: ]
......
find a function f and a number a such that 2*the integral from a to x of f(t)dt = 2sinx-1

hopefully you can understand the question written out like that, i appreciate any help! :)

-
f(t) will be in the form of cost
its integral times 2 is 2sint |a to x| = 2sinx - 2sina
so 2sina = 1, sina = 1/2, a = pi/6
so f(t) = cost, a = pi/6
