you make wt = pi/2, this obviously makes the time t = pi/2w, which is the time from when the switch opens to the voltage peak 1/4 of a cycle in to the oscillations.
So if you substitute this time of pi/2w seconds into the general form of the exponential decay equation where the value is -tR/2L
you get:
- piR/4wL

Hey Hugo,
This is incredibly useful and detailed analysis. Thank you, I will turn my attention to using the relevant equation to find the voltage 90 degrees into a cycle!
