WebIt makes sense, because normally when we're doing antiderivatives, you just take-- you know, when you learn the fundamental theorem of calculus, you learn that the integral of f with respect to dx, you know, from 0 to x, is equal to capital F of x. So it's kind of borrowing that notation, because this function of s is kind of an integral of y of t.
