how do you determine the effective value for complex waveforms that have different omegas such as 3cos(4t)+4sin(3t)?

The effective value of a complex waveform is the equivalent value of a DC (direct current) signal that would produce the same amount of power as the original complex waveform. It is also known as the root mean square (RMS) value or the average value of the waveform.
The effective value of a complex waveform can be calculated by taking the square root of the mean of the squared values of the waveform over one period. This can be represented mathematically as:
Effective value = √(1/T ∫T0 x(t)2dt)
Where T is the period of the waveform and x(t) is the function of the waveform at time t.
The effective value is important because it provides a single value that represents the total power of a complex waveform. This allows for easier comparison and analysis of different waveforms, and it is also used in calculating the power dissipated by electronic components in AC circuits.
The peak value of a waveform is the maximum value reached by the waveform, while the effective value takes into account the entire waveform over one period. The effective value is typically lower than the peak value, as it considers the negative portions of the waveform as well.
Yes, the effective value can be used for any type of waveform, including sine waves, square waves, and complex waveforms. It is a universal measure of the power of a waveform and is not limited to a specific type of signal.
