I am curious about the equation 2.7(a), and trying to prove it. So, I did my own calculation, and got a different result from the textbook. Did I make a right calculation? Also, I want to know where is the time t = tr? (Since fig 2.2 begins at time t = t(k-1), not t=0)
I didn't find the right solution from the Internet.
