Hmm Product Rule thing c:
Having trouble with that? :o

zepdrix · Answer

Oh they're all exponentials, might be easier to expand it first :o

zepdrix · Answer

What are you stuck on mare? c: come on speak up! :D
Having trouble differentiating an exponential that's not base e?

zepdrix · Answer

Oh nevermind U is your variable c:

zepdrix · Answer

mareee where you at :D

zepdrix · Answer

$$y(u)=(u^{-2}+u^{-3})(u^5+2u^2)$$$$y(u)=u^3+2+u^2+2u^{-1}$$
So she expands like that I guess? :O power rule yes no? :D
Mareeeeeeeeeeeeeeeeeeeeeeeeeee

sorry had to leave my computer for a few min. ive tried applying the product rule and simplifiying but i'm not coming up with the correct answer so i'm not sure where I'm going wrong

anonymous · Answer

is it better to simplify first and then apply the rule?

zepdrix · Answer

Either way is fine :D I just noticed that by expanding, we don't create any problems for ourselves.

zepdrix · Answer

Want me to run through it real quick? :O so you can just see where you made a mistake.

Oh yah i guess you DO want to expand it out first, cause it gets really messy otherwise :(
