@Ujjwal . I need to thank you for this. This was one formula I could never remember (I suck at mugging up stuff). But since I had to help you, I had looked it up yesterday, and so I could remember it today. And in an exam today there was a question similar to what you posted above. So you could guess what happened! Thanks! :)
