How to set up signal generator in lab to obtain an output voltage?
To me, this is confusing since the capacitor has not enough time to completely charge and discharge, so wouldn’t the peak to peak voltage change continuously? It would just make sense to define these limits for one period.

The bit of insight you might be missing is that you can start anywhere on the curve and the time taken to get from there to 63% of the way to V-max will be the time constant.

In the graph of Figure 1, for example, if we start at 63% we have 37% more to go to be fully charged. 63% of that = 37 x 0.63 = 23.3% so at the end of the second time constant the charge will have risen to 63 + 23.3 = 86.3% as shown on the graph. You can pick any starting point and the voltage will have risen 63% of the way from there to V-max after one time constant.
