This post will explain the notation used to denote partial derivatives in the output from Sage. It’s confusing at first, but a simple example will make it clear. Here is the input to Sage: var(‘x y’) function(‘test’, x, y) show(test(x, y)) show(diff(test(x, y), x)) show(diff(test(x, y), x, 2)) show(diff(test(x, y), y)) show(diff(test(x, y), y, 2)) […]

The easiest way to run Sage on Windows is with a virtual machine. Sage is a collection of tools that were primarily developed for UNIX-based operating systems (such as Solaris or Mac OS X) or UNIX-like operating systems (BSD, Linux, etc). Since a standard Windows installation lacks many of the features provided by a UNIX-like
