I have a test tommorrow... Any website you guys use for helping with math? I need to learn everything about derivatives basically...
 
It's hard for me... I did fine in all my other maths, but it's getting hard. I need to do decent on this qui to pass the class basically, but I don't think it will be too bad....
 
Umm... idk really... One I was having a hard time with that I am sure is simple..

-(1/X^2)

Is that qoutient rule?
 
Humm....you don't need to use Quotient Rule on that. You can re-write it as -(x^(-2)) and use Power Rule. Much simpler. You get: 2(x^(-3)) -> 2/(x^3)

edit: Quotient rule would work though.
