Hybrid homeschooling or flex-school [27] is a form of homeschooling in which children split their time between homeschool and a more traditional schooling environment like a school. [61] The number of students who participated in hybrid homeschooling increased during the COVID-19 pandemic .
Homeschooling constitutes the education of about 3.4% of U.S. students (approximately two million students) as of 2012. [needs update] The number of homeschoolers in the United States has increased significantly over the past few decades since the end of the 20th century.
In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic ; the other harmonics are known as higher harmonics .
In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.
Harmonic analysis is a branch of mathematics concerned with investigating the connections between a function and its representation in frequency.The frequency representation is found by using the Fourier transform for functions on unbounded domains such as the full real line or by Fourier series for functions on bounded domains, especially periodic functions on finite intervals.
