Hi Tian En, is this a Sec4 question? Or is there a "Hence" part? This question actually uses integration by parts, something you will learn in JC. For now, I'm not really sure how to solve this question just by using secondary school integration methods.

Hi, no it's not sec 4, it's ITE, sorry if you were confused, cause there weren't a category for ITE. :)
