Hi, I've been sitting on this more than an hour and still can't find the solution
I put this in a function grapher and it looks like the result should be , but I don't understand why this is true or how do I get to this solution. I assume that L'hospital should be used and supposedly there's another trick?
Thanks in advance
Thank you so much for the reply. However, I still don't understand how you did the second activation of L'Hospital. I tried to calculate the derivative of the numerator, and it seems insane, like it will take months to complete and require a whole notebook. Is there something I'm missing here?
I must admit, I simplified this with tech...not by hand. But, if you use the product rule for limits you can work it out.
That is, the limit of the product is the product of the limit.
Along with the log laws, it should simplify down.
Remember that , because it is ln(e)=1
Like I said, I did not work through this by hand. Too lazy.
Actually, you can greatly simplify the derivation if you put y=1/x in the limit.
so as
the equation becomes
applying l'hospital's rule, we get
which is
Since the left hand side is e, we apply l'hospital again to the right side
Applying l'hospital again, we get
