    Prove the inequality - 1\4(ln2)^2 <= sigma(2^n\(2^(2^n)))

    PAllen, Thank you for your response. I double checked it again and it's exactly as it is written on my paper. By the way, this is not that trivial, because in our test you are not allowed to use a calculator hence it's hard to calculate the value of (ln2)^2. One can still use some...

    Prove the inequality - 1\4(ln2)^2 <= sigma(2^n\(2^(2^n)))

    Homework Statement This is a question taken from an old exam so I am not sure to which subject in calculus it's connected to... Prove the inequality: \frac{1}{4(ln2)^2}\leq\sum\frac{2^n}{2^(2^n)} (sigma is from 1 to +inf, and the Denominator on the right side is (2^(2^n)) Homework...
