That is, there is only one independent variable. Partial differential equations or (PDE) are equations that depend on partial derivatives of several variables. That is, there are several independent variables. A second order, linear nonhomogeneous differential equation is. y′′ +p(t)y′ +q(t)y = g(t) (1) (1) y ″ + p ( t) y ′ + q ( t) y = g ( t) where g(t) g ( t) is a non-zero function.
