Abstract: The solving of nonlinear equation systems (e.g., complex transcendental dispersion equation systems in waveguide systems) is a fundamental topic in science and engineering. Davidenko method ...

Abstract: This paper proposes a novel non-iterative method to solve power system differential algebraic equations (DAEs) using the differential transformation, which is a mathematical tool able to ...

Trigonometric ratios are used to find the unknown side or angle of a right-angled triangle. There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each ...

This section focuses on the key features and methods for working with linear graphs. It demonstrates how to sketch graphs from rules, derive rules from graphs, and calculate key features such as the ...
