Question on integrals?

[twohaha]

If
(sin (x))/x = f(x), and that when x = 0, f(x) = 1

Solve, to the nearest decimal point:

∫(from 0 to x) ((sin (t))/t) dt = 1


I tried calculating that using my graphic calculator, and it gave me something around x = 1.1.
I am wondering if there is a formal way (like a proof) of working on this problem?

Thanks!

Your problem as posted does not make sense to me.

Please reread your post and problem - and post the problem EXACTLY as it was given to you.
