Find the length of the curve:
If I understand correctly, Length = integral from 1 to 2 of
So in this case, I need to find y' and substitute it in the formula and then find the integral.
Then I plug in y' into the formula to get (integral from 1 to 2)
L = I'm not sure where to go from here to make the integration work. I've been stuck on this for a while, so if anyone could help, I'd appreciate it!
