limit = e
Say that this limit exists and it equals A. Then $=\frac{1}{t}\ln(1+t)=\ln(A)$ The LHS is also $\frac{\ln(1+t)}{t}$ and when evaluating at t=0 you get 0/0, which is indeterminate and L'Hopitals can
be used. So $\ln(A)=\frac{\frac{1}{1+t}}{1}$ Try the limit again, and use algebra to solve for A again. edit: Th... | {"url":"http://mathhelpforum.com/calculus/63898-limit-e-print.html","timestamp":"2014-04-17T03:00:26Z","content_type":null,"content_length":"14977","record_id":"<urn:uuid:ae0ff62b-c236-484a-a62a-60b535fd798f>","cc-path":"CC-MAIN-2014-15/segments/1397609526102.3/warc/CC-MAIN-20140416005206-00633-ip-10-147-4-33.ec2.inter... |
