I already know the value of y, can you help me to find T? thanks :)

#y=-ln(-ln((T-1)/T))#

#T=1/(1-e^(-e^-y))#

Explanation:

Okay, let's solve this step by step.

#y=−ln(−ln((T−1)/T))#

#-y=ln(-ln((T-1)/T))#

To make things simpler, let's set #a=-ln((T-1)/T)#

#-y=ln(a)#

This equation basically means:

#e^-y=a#

Let's continue:

#e^-y=-ln((T-1)/T)#

#-e^-y=ln((T-1)/T)#

Once again, we can set a variable for #(T-1)/T# and get rid of the logarithm. Eventually, we will get:

#e^(-e^-y)=(T-1)/T#

#T*e^(-e^-y)=T-1#

#1=T-T*e^(-e^-y)#

#T(1-e^(-e^-y))=1#

#T=1/(1-e^(-e^-y))#

Since you know #y#, you can solve for #T#. If you see any mistakes, just comment. Hope this helps!
