Homogeneous Second-Order Linear Differential Equation

A Homogeneous Second-Order Linear Differential Equation is a Second-order Linear Differential Equation which equals to zero.

• Context:
  • It can be expressed as

[math]\displaystyle{ a_2(t)\frac{d^2y}{dt^2}+a_1(t)\frac{dy}{dt}+a_0(t)y=0\qquad\iff \qquad\frac{d^2y}{dt^2}+p(t)\frac{dy}{dt}+q(t)y=0 }[/math]

Alternatively, these expressions can be written as

[math]\displaystyle{ a_2(t)y''+a_1(t)y'+a_0(t)y=0\quad\iff \quad y''+p(t)y'+q(t)y=0\quad\textrm{with}\quad y''=\frac{d^2y}{dt^2},\;y'=\frac{d^2y}{dt} }[/math]
