Abstract: This paper investigates the stability of a delayed load frequency control (LFC) power system. Firstly, a dynamic LFC model is reconstructed to facilitate the development of a suitable ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...
