Do I do quotient rule for the 2nd part?
do u want me to show u?
Let's see if I know how
lol ok so u do it and then come back with the answer
y'=cosx + x(-4sinx)-(4cosx)(1) y'=cosx-4sinx-4cosx y'=-3cosx - 4sinx
did I do it right?
I forgot x^2 under it
ok I will do it again
but otherwise it is basically correct
umm no you it shld be -4xsinx
u included it the first time around
you are so right y'=cosx+ (- 4xsinx-4cosx)/x^2
ok ya this is fine
you cld techinically factor out a -4
but it isnt necessary. only if u want ur answer to look a lil neater
what should my final answer look like? I am always interested in making it look neater.
oh something is wrong with this drawing shreks
but whtvr u get the point i think
umm what level math r u in?
I am past graduate work in mathematics. I do this for fun!
lol r u serious???? cuz last time u helped with a hard questionand this is so simple so i thought i maybe was confusig u with someone else
|dw:1328586020836:dw| I think you dropped a sign.
No, I am very rusty in calculus so I am trying to challenge myself with calculus. I am pretty good in Algebra, Geometry, Precal, and so forth. But Calculus I am rusty.
oh u helped me in linear algebra
Ok if I can. It has been a while since I have seen Linear Algebra. That was one of my favorite courses. I am also, very rusty in proofs.
There are alot of very smart people here. Post your problem separately in case, I can not help you. That way someone might help along the way.
no i dont need help but u have helped me :D
