正弦波的缩放、拉伸与平移
本文简要介绍了如何调整标准正弦波 sin(x) 的幅度、频率和相位偏移。具体来说，针对一般函数 s(x)=A·sin(w·x+θ)，我们将探讨参数 A、w 和 θ 的调整对波形产生的具体影响。

The Artemis II mission launched to orbit the moon, similar to Apollo 8's preparatory mission in 1968. Like Apollo 13, it will swing around the moon rather than entering lunar orbit.
The article presents the exact closed-form solution for the nonlinear (large-angle) pendulum using Jacobi elliptic functions, contrasting it with the common small-angle approximation that uses sine functions. It explains how the exact solution involves elliptic integrals and Jacobi sn, cn, and dn functions, providing formulas for the angular displacement and period.
Researchers have developed an ultra-fast method for generating 1024-bit prime numbers using the Hilbert-Pólya spectral law. This approach significantly accelerates prime generation compared to traditional methods while maintaining cryptographic security standards.
The article discusses how the nonlinear behavior of a pendulum deviates from the simple harmonic oscillator approximation, particularly at large amplitudes where the period depends on the amplitude. It explains that this nonlinearity means the small-angle approximation (sinθ ≈ θ) breaks down, leading to longer periods than predicted by the linearized model.
A project argues that fundamental musical elements such as notes and harmony are not primitive building blocks but emergent structures. It introduces the concept that pitch is essentially rhythm sped up. A NotebookLM-generated podcast further explores these ideas.
