Software for recurrence relations
What software do you use and would recommend for solving recurrence relations?
For example mathematica has RSolve:
$ a(n+1)-2 a(n) = 1$ for $a(n)$:
RSolve[a[n + 1] - 2 a[n] == 1, a[n], n]
-> a(n) = c 2^(n-1)+2^n-1
Are there any good (preferably…

Need a computer application that solves a complicated single variable equation.
I have to solve the following equation for $r$:
$$298082 = 250000 (1 + r) + 25000 (1 + r)^{\frac{365 - 258}{365}}$$
... which simplifies to:
$$298082 = 250000 (1 + r) + 25000 (1 + r)^{0.293150685}$$
Back in my high school days I would solve this on…

No graph shown on Microsoft Mathematics
When I try to graph this formula, $$y=\sum^x_{n=1}[n*\sum^n_{m=1}\sin(\frac{m}{n})]$$, the graph shows nothing.
I thought it is possible that I input it in wrongly or the software can't solve this kind of summation equation but when I try with…
