What is the function of the “trigger” on an oscilloscope?

It stabilises the display and tells the instrument when to start measuring part of the signal.

Why is an oscilloscope useful for understanding how a circuit works?

Because it shows the signals the circuit produces and their characteristics.

What does “amplitude” measure?

The magnitude (or strength) of a signal.

How are a function generator and an oscilloscope used together during circuit testing?

The function generator sends a signal and the same signal into the oscilloscope; the oscilloscope then compares the input signal and the circuit’s output.
