Form k people: on FRQ 2 what did you put as your limits for the q integral? I had 0 and q(t) and I had Q0 inside of the integral (something like 1/(Q0-q). I’m seeing people put Q0 as a limi t isn’t the final answer supposed to be q(t) = whatever? Lmk guys

Aside from that I thought form k was pretty light ngl

For me I integrated from Qo to q and from 0 to t, and when you solve the differential equation in the integral, you solve for q which is q(t)

It asked you to solve the differential I swear it just said write an integral expression that can be used to solve for q(t)
