(a) The sine integral function is defined by where the integrand is defined to be 1 at t = 0. Express the solution y(x) of the initial-value problem y(1) = 0 in terms of Si(x).

(b) Use a CAS to graph the solution curve for the IVP for x > 0.

(c) Use a CAS to find the value of the absolute maximum of the solution y(x) for x >0.
