Probably. It's that or memorize the trig identity for sin(A) + sin(B) which is used to derive it. While the latter is more useful in general, the former is more likely to be expedient in the context of your current coursework.alexdr5398 said:
The sin function varies between + and - 1 as t varies, so what's its magnitude?. The rest are constant terms.alexdr5398 said:

It's the amplitude of the electric field strength that is being measured. That's the change in electric potential with distance, hence volts per meter as the basic unit. The amplitude here is not a physical distance, but a field strength.alexdr5398 said:

The amplitude of a combined signal refers to the maximum displacement of the signal from its resting position. It is a measure of the strength or magnitude of the signal.
To calculate the amplitude of a combined signal, you will need to measure the maximum displacement of the signal from its resting position. This can be done using various techniques such as using an oscilloscope or by measuring the peak-to-peak voltage of the signal.
Amplitude is typically measured in units such as volts (V) or decibels (dB), depending on the type of signal being measured.
Yes, the amplitude of a combined signal can change depending on the input signals and the type of combining operation being performed. For example, in amplitude modulation, the amplitude of the combined signal will vary based on the amplitude of the carrier signal and the modulating signal.
Knowing the amplitude of a combined signal is important for understanding the characteristics and strength of the signal. It can also provide valuable information for analyzing and processing the signal for various applications such as communication, data transmission, and signal processing.
