integration

ik e^x ( f(x) +f'(x)) would be used and f(x) would be (smthing)/x+1 cuz (x+1)^2 . how to fig out "smthing"

not neetards solving my maths doubts

CorrodedCoffinOP•12/12/25, 6:40 PM

i should kms

CorrodedCoffinOP•12/12/25, 6:41 PM

this more calculative approach

CorrodedCoffinOP•12/12/25, 6:41 PM

i was looking for some approximation approach

CorrodedCoffinOP•12/12/25, 6:41 PM

like i i was able to deduce 1/(1+x)^2 thing

ohh

Write bracket ke andar wala stuff as $(1-\frac{2x}{(x+1)^{2}})$ then change itto $(1-\frac{2}{(x+1)}+\frac{2}{(x+1)^{2}})$

Lance who?

SirLancelotDuLac•12/13/25, 4:09 AM

Now notice the last term is derivative of the first 2

SirLancelotDuLac•12/13/25, 4:10 AM

So the $(1-\frac{2}{(x+1)})$ is not the f(x) we need but the f(x) we deserve.

Lance who?

CorrodedCoffinOP•12/13/25, 4:45 AM

ohhhhh

CorrodedCoffinOP•12/13/25, 4:45 AM

that makes more sense
