of two or more simple harmonic motions, make other kinds of harmonic
motion. The motion of the pendulum bob of a clock is approximately

harmonic analysis, a mathematical method, sometimes referred to as that
of Laplace's Coefficients, which has for its object the expression of
an arbitrary, periodic function of two independent variables, in the
proper form for a large class of physical problems, involving arbitrary
data, over a spherical surface, and the deduction of solutions for
every point of space. The functions employed in this method are called
spherical harmonic functions. Thomson & Tait. -- Harmonic suture
