Bessel form A type ode \(ay^{\prime \prime }+by^{\prime }+(ce^{rx}-m)y=f\left ( x\right ) \)
Example \(ay^{\prime \prime }+by^{\prime }+(ce^{rx}-m)y=0\)

ode internal name "second_order_bessel_ode_form_A"

These are ode of the above form which can be converted to Bessel using transformation \(x=\ln \left ( t\right ) \).
