3. What is a constant of integration? Why does an answer to an integration problem involve a constant of integration?
4. Evaluate the integral sin x cos x dx by two methods: first by letting u = sinx, and then by letting u = cosx and then explain why the two apparently different answers obtained in part (a) are really equivalent.
5. If you want to evaluate an integral by u-substitution, how do you decide what part of the integrand to choose for u?
