Out of curiosity, what is the topic (in your book) from which you obtained the original problem? And what type of math book is it? (Stats, Linear Algebra, ... )

I don't know right now where excactly the problem is presented but it's somewhere in chapters covering polynomial functions, derivations and integrals. I'm studying electrical engineering, powerplants, communications etc..
