I currently run Sage math 5.9 through, VirtualBox Fedora linux virtual machine, on Microsoft Windows 7.
I performed the following calculations.
eq1i = integral( sqrt( 1 + 1/(4*x)) )
f(x) = eq1i.subs(x=x)
show(eq1i)
float( f(4) - f(1) )
As you may see, I did show(eq1i), to display the integral result in a more readable format. I'd like to to take a screenshot of my results in Sage, so then I can use an image editing program in Windows, such as MS Paint or Adobe Photoshop, and crop out the result of show(eq1i), result.
