Question

zed

Answer 1

(f/g)'= (gf'-g'f)/g²

Answer 2

Yeah, but apparently there's some new way that Zed invented

Answer 3

Not really

Answer 4

its not new, its just exactly what i just said. his trick is the thing above f and g are two separate functions

Answer 5

Yeah, it's the same. He invented nothing

Answer 6

I'm disappointed

Answer 7

but now that you're here, can you help me with it?

Answer 8

i gotta derive

\[(-x ^{4}+5)/e ^{x}\]

Answer 9

What do you need help with? lol

Answer 10

follow your own advice

Answer 11

That's pretty easy

Answer 12

im just wondering what im supposed to do with e^x squared

Answer 13

-4x^3+x^4-5/e^x

factor out the top and it should cancel

Answer 14

Leave it as e^x squared

Answer 15

It's not incorrect to leave it that way

Answer 16

zed, that can't be right...what you have...

Answer 17

how so?

Answer 18

unless e^x cancells

Answer 19

Yeah, e^x cancels top and bottom

Answer 20

Yeah, Paul, that wasn't a hard one at all

Answer 21

yeah. i got docked major points in cal 1 because i didnt always factor and reduce on the exams. its the difference between a C and a B

Answer 22

Z.E.D.

Answer 23

I was doing it in my head..Always look to reduce and cancel equivalents of one after taking derivative

Answer 24

Good job Zed

Answer 25

so the derivative of what i asked is itself?

Answer 26

No, Zed posted the solution...It's not exactly the same...An extra term appears

Answer 27

the derivative of e^x is always e^x

Answer 28

if that helps any

Answer 29

I think Paul needs step by step directions

Answer 30

ah i was so close, just a sign and x to the four.... i did know that the derivative of e^x is e^x thanks though... nah i didnt need steps so much, just was a bit lazy cause i thought i'd need a page to write the whole qquestion out, but ended up doing it in about 1/8th of a page.... yay us.

Answer 31

okay. if you need any more help just ask. differential calculus isnt too bad the algebra can get pretty tricky sometimes though

Answer 32

ALGEBRAAAAAAAAA! in the style of KHAAAAAAAN!!!!

Answer 33

Kilo Khan, Saifoo Khan, or Sal Khan?

Answer 34

whichever the one is from star trek

Answer 35

Ask Saifoo, he's part of the Khan family....He would know..

Answer 36

à la i mean, not in the style of.
