what is the derivative of \[x^{x}^{x}^{x}^{x}^{x}^{x}\]

OpenStudy (anonymous):

?

OpenStudy (aravindg):

simple!!

OpenStudy (aravindg):

put y=x^y

OpenStudy (aravindg):

do logarithmic differentiation

hartnn (hartnn):

but is it till infinity ? then y=x^y would work

OpenStudy (anonymous):

is that\[\huge x^{x^{x^{x^{...}}}}\]

OpenStudy (anonymous):

y=x^x^x^x^x^x^x lny=(x^x^x^x^x^x) lnx

OpenStudy (anonymous):

Now, do differentiation

OpenStudy (anonymous):

yes muushla

OpenStudy (aravindg):

i assumed @Zekarias meant that

hartnn (hartnn):

then y=x^y will definately do...take log on both sides.

OpenStudy (anonymous):

then, lny=y lnx

OpenStudy (anonymous):

Blunder

OpenStudy (aravindg):

@Joseph91 what blundeR?

OpenStudy (aravindg):

@Zekarias did u get the answer?

OpenStudy (anonymous):

It is-not an infinite series

OpenStudy (anonymous):

IS it (1-y lnx)/x

OpenStudy (anonymous):

yap thanks

OpenStudy (anonymous):

LET y=x^x^x^x^x... then lny=ln(x^x^x^x^x...) lny=ylnx d(lny)/d(x) = d(y lnx)/dx

OpenStudy (anonymous):

This will lead to the solution

OpenStudy (anonymous):

yes thats correct mr .sauravshakya

OpenStudy (anonymous):

But this is not suit for the questioon
