use chain rule
OpenStudy (anonymous):
omg taht is sooo confusing wel atleast how my teacher explains it
OpenStudy (anonymous):
y'=e^e^x.e^x
OpenStudy (anonymous):
is taht a multiplication symbol btwn e^e^x and e^x?
OpenStudy (anonymous):
yes

\[y=e ^{e ^{x}}\]
OpenStudy (anonymous):
do u know chain rule?
OpenStudy (anonymous):
Just break it down, derivative of e^x would be e^x, which is the exponent for the lower e...therefore you would multiple e^e^x by e^x.
OpenStudy (anonymous):
i knw teh chain rule but idk how 2 use it
OpenStudy (anonymous):
For the second derivative you need to chain rule and product rule

OpenStudy (anonymous):
i know teh product rule
OpenStudy (anonymous):
so im confused about this chain rule
OpenStudy (anonymous):
y'=e^e^x.e^x u understand this?
OpenStudy (anonymous):
now product rule
OpenStudy (anonymous):
: f'(x) g(x) is taht wat u did?

(fg)'=f'g+fg'
OpenStudy (anonymous):
Uzma please correct me if I made a mistake but the second derivative is y''= \[e^x *e^e^x + (e^x)^2 * e^e^x \]
OpenStudy (anonymous):
u r right jm
OpenStudy (anonymous):
so the anwer to the frst der is e^e^x * e^x
and teh 2nd der is wat is written above?
OpenStudy (anonymous):
Yes.

OpenStudy (anonymous):
yea
OpenStudy (anonymous):
but make sure that u understand it
OpenStudy (anonymous):
can u explain teh chain rule
OpenStudy (anonymous):
if u have y=f(x)^g(x)
the y'=[f(x)^g(x)]'.[g(x)]'
OpenStudy (anonymous):
in this case it was f(x) ^g(x) to another exponent....so then how wud u modify the formula

OpenStudy (anonymous):
no modification, just classify f(x) and g(x)
OpenStudy (anonymous):
wat do u mean?
OpenStudy (anonymous):
f(x)=e^e^x and g(x)=e^x
apply the rule
OpenStudy (anonymous):
ohhh i get it.....
OpenStudy (anonymous):
so the der of e^e^x is just e^e^x? since e^x is e^x

\[y[x]\text{=}e^{e^x} \]\[y'[x]=e^{e^x+x} \text{Log}[e]^2 \]\[y\text{''}[x]=e^{e^x+x} \text{Log}[e]^3 \left(1+e^x \text{Log}[e]\right) \]
OpenStudy (anonymous):
whoah...now u introduced logs..im confused....
OpenStudy (anonymous):
der of e^e^x is e^e^x, right?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
the what is exponent?
e^x

OpenStudy (anonymous):
and its der ise^x
multiply both
OpenStudy (anonymous):
inst it just e^x^2
OpenStudy (anonymous):
no
OpenStudy (anonymous):
idk
