 Oct 27 comment Show that there is a $S \in L(V )$ and $v_0 \in V$ such that $T(x) = S(x) + v_0,$ $\forall x \in V$ Linear operators space from $V$ to itself. Nov 3 comment Find the value of $\sqrt{10\sqrt{10\sqrt{10…}}}$ Nice And interesant resolution! Oct 31 comment Am I doing something wrong with this improper integral? They say that I'm using in a wrong way Barrow's rule. Oct 29 comment Calculating indefinite integral? At last line your answer differs with the answer that I put when I asked my question. :) Jul 1 comment Solving logarithmic equation? Textbook says that $\sqrt{2}-1$ is one solution. Jul 1 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. May 27 comment How do I $n\lambda ^n$ tends to $0$? I was thinking about this expression in this form today with a friend. Thanks :) May 26 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 $$\frac{ln(\lambda ) \lambda^x}{\frac{-1}{x^2}}$$ Apr 14 comment Prove that a sequence is a Cauchy sequence. What happens if we have $|s_{n+1}-s_n|< \frac{1}{n}$? Apr 14 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. Jan 16 comment Where is a flaw in these logical implications? How did you derived that \$a
