Question

show me how to get the derivative of f(x) = 5x/(1+x^2)

Answer 1

please

Answer 2

use this, dy/dx= (v du- u dv)/v^2

Answer 3

i just fluttering tried that whats fluttering v and u

Answer 4

u is the numerator, while v is the denominator. .

Answer 5

i know i fluttering know but i can't get the right fluttering answer no matter WHICH of ALL the SAME but VARIOUS formulas I use that are for obtaining the fluttering derivative. so using that one i get fluttering -5/3, which is wrong. plus every formula seems to produce a different fluttering answer. how stupid can i be. god fluttering damn it.

Answer 6

let me see your solution. .

Answer 7

well uh assuming that would mean that u = 5x and v = (1 + x^2),

Answer 8

i get [(1 + x^2) * d(5x) - 5x * d(1 + x^2)] / (1 + x^2)^2

Answer 9

etc idk i scribbled it all out and i'm tired of looking at it just show me please

Answer 10

you already got the process. . then find the derivative, and apply algebra. .

Answer 11

no i got nothing pleas ejust fluttering spell it out for me i need a logical fluttering visual and thorough explanation

Answer 12

ooh, this is partial fraction. . lol . i don't know how to compute partial fraction. . .

Answer 13

i could flutter my own brain over a million times and just be more inclined to get more confused overall that way or just see HOW the answer is derived -- like checking the answers in the back of the fluttering book, for reference, except when that doesn't make it click for you or help you understand, then you're in a bind, and you need a stronger hint, to whatever degree stronger it needs to be -- but if you get that you won't just fluttering rack your own brain and die first and burn out get me?
