While graphs for cosine and sine functions are similar, those for tangent functions differ significantly from them, sharing only in that they show periodicity and symmetry. Recall \(\tan(x)= ...

Abstract: A periodic graph models various natural and artificial periodic patterns with repetitions of a given static graph, and have vast applications in crystallography, scheduling, VLSI circuits ...

Almost periodic functions serve as a powerful conceptual framework in analysing differential equations whose coefficients or forcing terms exhibit recurrent behaviour over time. Rooted in the ...
