That particular example is almost easier to do by hand, but one way in Sage is:
f=(sin(5*pi*x))^6 solve(diff(f,x)==0,x) which gives [x == 0, x == (1/10)] Of course there are a lot more solutions than those in this case; those might have been chosen by taking one branch of the inverse sine. -M.Hampton On Mar 7, 2:47 pm, Mike Brown <[email protected]> wrote: > Hello, > > I want to say that I just learned about Sage.
