trigonometric functions
On random almost periodic trigonometric polynomials and applications to ergodic theory.
The situation is analogous to the higher-order trigonometric factors () = 2p+1 : they have the advantage of being local but their order is finite.
The seasonality of births was examined in three 5-year periods using the technique of trigonometric regression.
This is in contrast to the trigonometric functions that traditionally have been associated with waves.
Also, the trigonometric functions are replaced by hyperbolic ones.
Then it becomes a trivial matter to average the trigonometric functions.
For the special example (3.1) where the curvature and torsion are simple trigonometric functions, we can solve the leading-order equations explicitly.
A very important feature of the trigonometric system that made it attractive for the representation of periodic functions is orthogonality.
