(a) Use a CAS to graph the solution curve of the initial-value problem in Problem 47 on the interval [0, ˆž).

(b) Use a CAS to ­nd the value of the absolute maximum of the solution y(x) on the interval.

Data from problem 47

The sine integral function is de­fined as

where the integrand is defi­ned to be 1 at x = 0. See Appendix A. Express the solution of the initial-value problem

x³ dy/dx - 2x²y = 10sinx, y(1) = 0

in terms of Si(x).
