Function linear2

linear2(
    a: number | ((t: number) => number),
    b: number | ((t: number) => number),
    c: number | ((t: number) => number),
): ChalkboardODE
Defines a second-order linear scalar ODE: y'' = a(t)y' + b(t)y + c(t).
Parameters
- a: number | ((t: number) => number)
  Coefficient a(t) or constant a.
- b: number | ((t: number) => number)
  Coefficient b(t) or constant b.
- c: number | ((t: number) => number)
  Coefficient c(t) or constant c.
Returns ChalkboardODE
