Periodic Orbits on a Surface of Revolution
Since the constant part of the right member of (28) has exactly the same period as the constant in the complementary function then non- periodic terms will
Even and Odd Functions
containing both cosine and sine terms as well as a constant. Thus an even function has no sine terms in its Fourier series.

Linear Differential Equations with Almost Periodic Coefficients
viously stated. Here aq+1(t) is an a. p. function which again has no constant term and whose least frequency is greater than (q + 1) y. Since the aj (t) are.
