Question

Differentiate:

Answer 1

\[\LARGE y=\frac{e^x}{1+x}\]

Answer 2

What class are you in?

Answer 3

And for this one just use the quotient rule.

Answer 4

So..
\[\LARGE \frac{(1+x)(e^x)-(e^x)}{(1+x)^2}\]
\[\LARGE y'=\frac{x}{(1+x)^2}\]

Answer 5

And I'm in calc 1.. again T_T

Answer 6

gg

Answer 7

And check your numerator.

Answer 8

And I never learned about e^x in calc 1 .. T_T

Answer 9

Yea, I'm missing an e^x.. just noticed >.<

Answer 10

..Which is weird..because it seems like every other school did... T_T

Answer 11

lol..... T_T

Answer 12

Can anyone here help me with advanced calc?

Answer 13

\[\frac{ d }{ dx }\frac{ e ^{x} }{ 1+x }=\frac{ (1+x)e ^{x}-e ^{x} }{ (1+x)^{2} }=\frac{ e ^{x}+xe ^{x}-e ^{x} }{ (1+x)^{2} }\]

Answer 14

and that can be reduced to \[\frac{ xe ^{^{x}} }{(1+x)^{2} }\]

Answer 15

So, Luigi, you're missing an e^x.

Answer 16

(As you yourself said.)

Answer 17

Anna: Please post your question in the usual way; if someone can help you, you'll likely hear from that person (or persons).

Answer 18

xe^x/(1+x)^2
