Visualizing RMS of a Rectified AC Signal

This example demonstrates how an AC waveform is rectified (effectively taking its absolute-value form) and then summarized by its root-mean-square (RMS) value, interpreted as an equivalent magnitude. It highlights the geometric/graphical behavior of the rectification process over one or multiple periods. Key concepts include trigonometric modeling (e.g., cosine/periodic functions), rectification, and the RMS statistic defined via the square, time averaging over a period, and a final square root. Construction uses GeoGebra objects from the summary: omega, T, and t to represent angular frequency, period, and time; I_O and function components f, g for the original waveform; additional parameters/auxiliaries (b, c, d, e, h, p, c_1, a, i) to build the rectified expression, compute squared values and the averaging step, and obtain the RMS result. Suitable for high school through early undergraduate teaching, especially in math modeling, probability & statistics (mean-square ideas), and signals/electrical engineering demonstrations.
