Exercise 1.9.9

Answers

First remove a rectangle of 1’s, touching the parabola where the slope = -1. This rectangle has a rank of 1. On the top, we have $N - \frac{3}{4} N = \frac{1}{4} N$ rows, they are independent, on the right we have $N - \frac{1}{2} N = \frac{1}{2} N$ columns, which are independent too. So the leading term in the rank is: $\frac{1}{4} N + \frac{1}{2} N = \frac{3}{4} N$
