RETRACTED ARTICLE: Trigonometric polynomial solutions of Bernouilli trigonometric polynomial differential equations

Analysis and Mathematical Physics, 2023
The paper investigates two types of real trigonometric polynomial equations: \[ A(\theta)y'=B_1(\theta)+B_n(\theta)y^n \] and \[ A(\theta)y^{n-1}y'=B_1(\theta)+B_n(\theta)y^n \] The authors focus on the first equation and demonstrate that when $n\geq 4$, it has a maximum of 3 real trigonometric polynomial solutions if $n$ is even and 5 real ...

Solution of Dual Trigonometrical Series Using Orthogonality Relations

SIAM Journal on Applied Mathematics, 1970
Abstract : The unknown coefficients in dual trigonometrical series are found by a method which eliminates the need for assuming initially the forms of the expressions for the coefficients, and also for differentiating the original series term by term.

Trigonometric equations and their solution

1984
It is often useful to express a cos θ + b sin θ as a single term such as r cos (θ − γ), where r is positive. This is possible if we can find r and y such that $$\begin{gathered} r\cos \left( {\theta -\gamma } \right)\equiv r\left( {\cos \theta \cos \gamma +\sin \theta \sin \gamma } \right) \hfill \\ \quad \quad \quad \quad \;\;\;\equiv a\cos \theta
