In the last step we took the reciprocals of the three positive terms, reversing the inequities. Squeeze: The curves y = 1 and y = cos θ shown in red, the curve y = sin( θ )/ θ shown in blue. We conclude that for 0 < θ < 1 / 2 π, the quantity sin( θ )/ θ is always less than 1 and always greater than cos(θ).
To step from n to n + 1, generate a vector v uniformly distributed on the n-sphere S n, embed the n × n matrix in the next larger size with last column (0, ..., 0, 1), and rotate the larger matrix so the last column becomes v. As usual, we have special alternatives for the 3 × 3 case. Each of these methods begins with three independent random ...
