For a pair of expressions ($A,B$), I need to determine whether $A$ is upper asymptotic, tight bound, or lower asymptotic of $B$. For example:

$$A = n^{\log(c)}$$ $$B = n^{sin(n)}$$

What (free) software and (simple) commands could I use to graph these?

I am not very experienced with using software to plot. Thank you.

You can use Wolfram Alpha, like this, or Function Plotter. I prefer the latter for relatively simple expressions, because you can interactively zoom in or out with your mouse-wheel. Just add the function on the right (by default, it displays $x^2$).

As far as I know fooplot only plots functions, not sequences. In WA you can probably do both.

  • $\begingroup$ Thanks, Nameless, but I need to plot at least two functions at the same time, and it doesn't seem WA can do that..? $\endgroup$ Commented Sep 11, 2013 at 0:32
  • $\begingroup$ Actually you can, for example wolframalpha.com/input/?i=plot+x^2%2C+sqrt%28x%29 (copy entire link). Same for fooplot: just add another function on the right. $\endgroup$ Commented Sep 11, 2013 at 8:15
