Abstract

In this note we shall show that Mathieu’s equation for x(t)

may be efficiently and accurately integrated by the Runge-Kutta (RK) method under the initial conditions

for the even Mathieu functions cen(t, q) → cos (nt) as q → 0 and

for the odd Mathieu functions sen(t, q) → sin (nt) as q → 0.
