Question 2 (5 marks). There is often more than one way to achieve certain goal in life. A little bit of exploration goes a long way. The same can be said in mathematics. In this question, we explore and compare different integration techniques. Note that “rewrite an integral" and "transform an integral" have the same meaning. Consider the integral x sin²(x) cos(x) dx. (1) Rewrite (or transform) the integral using integration by parts. There is no need to fully evaluate the integral in this part. (2) Rewrite (or transform) the integral using the substitution rule. There is no need to fully evaluate the integral in this part. (3) Continue from part (1) or (2) to fully evaluate the integral in (★)
