The Bessel(ODE, y(x)) command finds the solution of a second order linear ODE in terms of Bessel functions.

Use the option output=steps to make this command return an annotated step-by-step solution. Further control over the format and display of the step-by-step solution is available using the options described in Student:-Basics:-OutputStepsRecord . The options supported by that command can be passed to this one.
