Thanks a lot for your replies guys In terms of me seeing them both as too mathematical I had to put it down to that through plain ignorance as I didn't understand why I've had such difficulty understanding them both, though I realise they aren't complicated. I will go over what you've both said again with some books and see where I get. I appreciate it!

Hi guys In my studies I've had great difficulty understanding these two equations; I'm not mathematically minded, and however much I read over our notes or ask lecturers for help, its not clicking. If there is a kind and clever person on here who's willing to talk me through these equations with examples I'll be so grateful! Thanks a lot
