But you'd be looking at two different things. When looking at a math textbook on differential equations, you're looking at why a class of expressions constitutes a solution to a differential equation. Looking at code, all you'd get is the mechanical how something is computed, and you'd have to take it on faith that what was computed constituted the solution you were looking for.
