 Feb11 comment Sequence $a_{n+1}=\sqrt{1+\frac{1}{2}a_n^2}$ Some who doesnt know the master theorem is there an alternative solution ? Feb10 comment Sequence $a_{n+1}=\sqrt{1+\frac{1}{2}a_n^2}$ the problem isnt for a_{n+1) -2 but for first n=1 Feb10 comment Sequence $a_{n+1}=\sqrt{1+\frac{1}{2}a_n^2}$ for which one ? Feb10 asked Sequence $a_{n+1}=\sqrt{1+\frac{1}{2}a_n^2}$ Feb5 accepted Calculate this limit $\lim_{n\to \infty } \, \frac{(-1)^n \left(n^2 \sin (n)+2 n\right)}{{n^2}+3}$ Feb5 comment Calculate this limit $\lim_{n\to \infty } \, \frac{(-1)^n \left(n^2 \sin (n)+2 n\right)}{{n^2}+3}$ It seems it doesnt however problem asks to be found. So I guess I have to proove that it doesnt exist Feb5 asked Calculate this limit $\lim_{n\to \infty } \, \frac{(-1)^n \left(n^2 \sin (n)+2 n\right)}{{n^2}+3}$ Feb5 comment Integral $\int{\frac{x^5}{\sqrt{x^2+7}}}dx$ after posting this I though of using this transform. I am trying it now.. Feb5 asked Integral $\int{\frac{x^5}{\sqrt{x^2+7}}}dx$ Feb4 accepted Evaluating $\int{\frac{1}{\sqrt{x^2-1}(x^2+1)}dx}$ Feb4 comment Integal $\int\left(\sqrt{4-9x^2}\right)^3 dx$ I had this in mind but seemed complex. Maybe there other substitutions too.. (initial) Feb4 asked Integal $\int\left(\sqrt{4-9x^2}\right)^3 dx$ Feb3 comment Limit of sequence 3 It seems that taking root test for series works. Do root test and take $7^n$ out .Then limit to ifninity of $\sqrt[n]{1+n/7^n}$ should be 1.
