Have an exam and need help with these 2 before im off to bed, im not sure where to start so if someone could help me in the right direction id appreciate it. Thanks :]
You can first write ln(e^w/(8+e^w)) = ln e^w - ln(8+e^w) =
w - ln(8+e^w) , with w = theta, and the derivative of this is:
1 - e^w/(8+e^w) = 8/(8+e^w)
and
