A number of graphics output libraries have been brought to my attention, but none seem to go right to PNG or include basic equations. In this case SymPy automatically rewrote the input expression and gave its canonical form, which is x + 1 once again. The emphasis will be on the basics and understanding the resulting decision tree. The problem is actually a solid argument for scaling differential equations before asking SymPy to solve them since scaling effectively reduces the number of parameters in the equations! signal processing people to tend put (strong) expectations on outputs, and strive to find systems that convert inputs appropriately. So far, I believe my best option is to use Expr. lambdify acts like a lambda function, except it. doit()/dx. I’d like to do this with something like Markdown.

The pprint module provides a capability to “pretty-print” arbitrary Python data structures in a form which can be used as input to the interpreter. ):. If the formatted structures include objects which are not fundamental Python types, the representation may not be loadable. Consider the following engineering statics problem which can be solved with symbolic math and SymPy. If you have access, it's worth it to write your own Maple or Mathematica script to do this for you for an arbitrary metric.
