Where does the power rule come in?

Basically.. forget the power rule. you will learn that later. For now you must use this method :D ... But once you learn the power rule, you will be able to differentiate that in 5 seconds.

very good question, there is a little bit of history to this... basically two guys were inventing calculus near the same time, so lots of different notations came about. These all mean the same thing: dw:1351144085607:dw

So basically you have to memorize these rules?
 2 years ago

baldymcgee6 Group TitleBest ResponseYou've already chosen the best response.2
haha, you will have to yes... But it will become second nature. For this rule, just drop the exponent and minus one.
