Shulman (1987) defined pedagogical content knowledge as the knowledge required to transform subject-matter knowledge into curricular material and pedagogical representations. This paper presents the results of an exploratory case study that examined a secondary teacher's knowledge of sine and cosine values...

While Sine and Cosine functions were originally defined based on right-angle triangles, looking at that point of view in the current scenario isn’t really the best thing. You might have been taught to recognize the Sine function as “opposite by hypotenuse”, but now it’s time to have a...
With its core idea that a function, often a signal, can always be decomposed into pure sine and cosine functions, the FT is foundational in spectral pattern analysis3,4,8,61. However, not all functions f(t) can be decomposed—only those that live in the Lebesgue space L2(0, 2π). ...

This research endeavor is dedicated to enhancing data confidentiality in internet transmissions by strategically employing Hash functions and harnessing the advantageous attributes of chaos. These attributes, characterized by inherent complexity, sensitivity to initial conditions, and resilience to attacks, are...
Sine-cosine transformations on the interval 0.5 T ≤ t ≤ 0.5 T , which are equivalent to a cosine transformation on the interval 0 ≤ t ≤ T , are considered. Relationships for the error variance of signal reconstruction are obtained. Depending on the a priori information on the signal, ...
Unlike Fourier analysis that produces a series of sine and cosine functions of fixed amplitudes to represent each frequency constituent in the signal, the Hilbert–Huang spectrum approach is based on the computation of instantaneous frequency from Hilbert transformation of the signal. Generally, the ...
Synopsis * The Fu Liye transform can represent a function satisfying certain conditions as trigonometric functions (sine and / or cosine functions), or a linear combination of their integrals. In different research areas, the Fu Liye transform has several different variant forms, such as the ...
