How to enter a differential equation
The coefficients of your equation must be quotients
of polynomials with rational numbers as coefficients
(no parameters or symbols other
than the independent variable).
They must be entered using standard infix syntax, using the operators
+,-,*,/. You must use * for the product, e.g.
An empty box means that the corresponding coefficient is 0.
Numeric constants must be entered as quotients of exact integers
and not as floating point numbers,
e.g 1/2 and not 0.5.
The independent variable can have an arbitrary name, it must not necessarily
For security reasons, it is however limited to one character only.
