P4 Topic 6: Second Order Differential Equations
Particular integral 2
Second order differential equations of this form:.
have solutions with two parts: the complementary function and the particular integral. The type of particular integral depends on the nature of f(x). The following display shows examples where f(x) is a trigonometrical function.

Summary When f(x) is trigonometrical, the trial solution is y = psin x +q cos x This page uses HotEqn.
