Is that:
\[sinh{3x} \cdot e^{4x}\]
?
OpenStudy (anonymous):
what to do with that?
OpenStudy (anonymous):
if the eq is like traxter wrote, the exchange sinh(3x) as a exp function.

hartnn (hartnn):
can u find the n th derivative of e^{ax} ?
OpenStudy (anonymous):
sin h 3x e^4x
find the nth derivative will u derive it
OpenStudy (anonymous):
can u find the n th derivative of e^{ax} ?
form:a^n e^ax
OpenStudy (anonymous):
e^ax nth derivative is (a^n)e^ax
OpenStudy (anonymous):
maybe it is easy to change sinh3x in a exp function

Leibniz' theorem/ binomial stuff will work for u\[(uv)^{(n)}=\sum_{k=0}^{n}\left(\begin{matrix}n\\k\end{matrix}\right)u^{(n-k)}v^k\]
OpenStudy (anonymous):
sinh3x = (e^3x - e^-3x)/2
OpenStudy (anonymous):
so the given eq is ruduced as (e^7x - e^x)/2
OpenStudy (anonymous):
then you apply a e^ax derivative rule
OpenStudy (anonymous):
can u explain breifly plz

then the answer is [(7^n)e^7x - e^x]/2
OpenStudy (anonymous):
the definition of the sinhx = (e^x - e^-x)/2. we promised it
OpenStudy (anonymous):
ignore my comment
hartnn (hartnn):
@shambavi ask if u still don't get it.
OpenStudy (anonymous):
@LeeYeongKyu heyy thankxxxx i got it

if you want to know why sinhx = (e^x - e^-x)/2 use euler theory
