Derivatives

[viscid tree]

Is theree any tip anyone can give me when deriving stuff like this? i have a test tomorrow and i cannot be fumbling

[viscid tree]

the goal is to show f'(x) = 1-a....

[quartz sand]

just use the chain rule

[viscid tree]

chain rule?

[quartz sand]

use product rule and chain rule. there is nothing uch to it

[viscid tree]

i do math in french hol up lemme look that up

[quartz sand]

like d/dx[f(g(x))]= f'(g(x))*g'(x)

this will let u recall

[viscid tree]

but here what is g(x)?

[quartz sand]

-x^2

for e^-x^2

[viscid tree]

i was gonna do f'(x) = 1 + e^u

[quartz sand]

let e show u a soultion

[viscid tree]

thanks by the way its 11pm and i thought i was gonna be fried

[quartz sand]

its 9 for e

[drowsy rover]

It's 7pm here

[viscid tree]

11 here

[viscid tree]

hm?

[viscid tree]

francais?

[drowsy rover]

Non

[viscid tree]

ohh nvm

[viscid tree]

...

vraiment?

[quartz sand]

this is chain rule

first i deriated e then i derivated -x^2

with product rule

[viscid tree]

first line the + e^x-2 is the derivative of g right?

[drowsy rover]

Quoi

[viscid tree]

merde pardon jdor debout

[viscid tree]

quelle region/

?

[quartz sand]

-x^2 is g and e is f

[drowsy rover]

Ohh oui

[quartz sand]

for e^-x^2

[viscid tree]

oh alright

[quartz sand]

u got the solution?

[drowsy rover]

Côté d'ivoire

[viscid tree]

i js dont understand the

[viscid tree]

sympa

[drowsy rover]

Et toi

[viscid tree]

de base je suis du sud mais je vis au Vietnam

g dst de maths demain chui ds la merde

[quartz sand]

x is derivated and e^-x^2 is left as it is. in product rule

[drowsy rover]

D'accord bon

[quartz sand]

u' * v + v' * u. its the x' * e^-x^2

u got it?

[viscid tree]

e^-x^2 is v'?

[quartz sand]

no its u

[viscid tree]

oh yeah alright

[quartz sand]

see its not derivvated

[viscid tree]

yeah i see

[quartz sand]

u got it?

[viscid tree]

i think so? hah

[drowsy rover]

Tu apprends Latex

[quartz sand]

ok

[viscid tree]

Latex?

[drowsy rover]

Oui

[viscid tree]

c'est quoi?

[viscid tree]

thanks lots by the way

[drowsy rover]

It helps you write complex mathematical formula, c'est vraiment bon

[viscid tree]

hm tu crois je peux apprendre ca een 1h?

jai encore la geometrie ds le repere

jy comprend que dalle avec lees histoires de coplainaires orthogonalite etc

[drowsy rover]

Non, impossible

[viscid tree]

ah merde

bon

[drowsy rover]

Tu n'as pas du temps

[viscid tree]

malheureusement

eitherways meerci je dois te dire aurevoir chef

je v continuer a reviser

[drowsy rover]

D'accord salut
