And this is almost in a form. We're used to seeing it where the x is the upper bound. And we already know what happens. We can swap these two bounds, but it will just be the negative of that integral. So this is going to be equal to, let me rewrite it, the negative of the definite integral from c to x of cosine t over t dt. And then we have plus the definite integral that goes from c to x squared of cosine t over t dt. So all we've done is we've rewritten this thing in a way that we're used to applying the fundamental theorem of calculus.
