 Nov3 comment Find the value of $\sqrt{10\sqrt{10\sqrt{10…}}}$ Nice And interesant resolution! Oct31 comment Am I doing something wrong with this improper integral? They say that I'm using in a wrong way Barrow's rule. Oct29 comment Calculating indefinite integral? At last line your answer differs with the answer that I put when I asked my question. :) Jul17 comment How can I define a “formula” for general term of a sequence with some given values? No, I forget that, that's the reason for ask my question. Jul17 comment How can I define a “formula” for general term of a sequence with some given values? Well, I know about Lagange's Polynomial, but I read an indian book about this topic, and they don't use that Polynomial there. Jul1 comment Solving logarithmic equation? Textbook says that $\sqrt{2}-1$ is one solution. Jul1 comment Solving logarithmic equation? In the textbook, solutions are $\sqrt{2}-1$ and $-\sqrt{2}-1$. I know this "hunting lion" method, but exact solutions exists. May27 comment How do I $n\lambda ^n$ tends to $0$? I was thinking about this expression in this form today with a friend. Thanks :) May26 comment How do I $n\lambda ^n$ tends to $0$? Yes: $\lim_{x\rightarrow \infty}\frac{\lambda^x}{\frac{1}{x}}$ gives me the indetermination "$0$/$0$" and I need to see the behaviour of $$\frac{ln(\lambda ) \lambda^x}{\frac{-1}{x^2}}$$ Apr14 comment Prove that a sequence is a Cauchy sequence. What happens if we have $|s_{n+1}-s_n|< \frac{1}{n}$? Apr14 comment If $x + \frac{1}{x} = k$, what's the value of this sum? The initial problem is with $k=3$, but I'm thinking about consequences if $k$ is a real positive number. Jan16 comment Where is a flaw in these logical implications? How did you derived that \$a
