How do you differentiate y = (ln x)^ln x? - Socratic
May 30, 2017 · So, we turn #(lnx)^(lnx)# into #e^((ln(lnx))(lnx))#. This works because, due to raising e to any power is an inverse function to taking the natural log of any number, #e^ln(x)=x# for any x. This may seem like a more complicated function we have made to take the derivative, but trust me, it makes thins simpler.

What is the derivative of #x^(lnx)#? - Socratic
Nov 6, 2016 · The derivative of x^(lnx) is [(2*y*(lnx)*(x^(lnx)))/x] let y =x^(lnx) There are no rules that we can apply to easily differentiate this equation, so we just have to mess with it until we find an answer. If we take the natural log of both sides, we are changing the equation. We can do this as long as we take into account that this will be a completely new equation: lny=ln(x^(lnx)) …

How do you find the limit lnx/x as x->oo? + Example - Socratic
Nov 5, 2017 · The question is to find the value of #lnx/x# where #x to oo# If we let #x=oo# then #lnx/x=(oo)/(oo)# #=# Undefined . So now we can apply L'Hospital's rule by differentiating the numerator and denominator individually. So, #d/dxlnx=1/x# and #d/dxx=1# #lim_(x -> oo)(1/x)/1# #lim_(x -> oo)1/x# Now we let #x=oo#

What is the derivative of #e^(lnx)#? - Socratic
May 29, 2017 · 1 We can also do this without first using the identity e^lnx=x, although we will have to use this eventually. Note that d/dxe^x=e^x, so when we have a function in the exponent the chain rule will apply: d/dxe^u=e^u*(du)/dx. So: d/dxe^lnx=e^lnx(d/dxlnx) The derivative of lnx is 1/x: d/dxe^lnx=e^lnx(1/x) Then using the identity e^lnx=x: d/dxe^lnx=x(1/x)=1 Which is the …
