Hello, I'm new to Sage and this group.
I have been doing some simple experimentation with integration in order to get up to speed. One thing I attempted was to try and calculate an integral, attempting to reproduce the problem described on this page: http://mathforum.org/library/drmath/view/52038.html Here is how I gave the problem to Sage (V4.1.1 under Windows): f=sin(x) g=f.diff(x) h=(sqrt(g^2+1)) j=integral(h,x,0,2*pi) j Here is the response from Sage: integrate(sqrt(cos(x)^2 + 1), x, 0, 2*pi) This looks like Sage can't perform the integration, and it seems the sqrt is the problem, although it doesn't flag any sort of error. In the web page I give above, the problem is solved with MAPLE... so I am not sure why Sage has a problem with it? I suspect I am missing something or doing something stupid. Can anyone enlighten me please?
