Talk:Brahmagupta matrix

Hi. The Current Brahmagupta matrix formular is not accurate. It lacks a power sign. Please refer to Wolfram Website. Regards, Minh Tue.

I agree. See the B^-n to see what it should be. So I fixed it. Missing ^n is now in place. —Preceding unsigned comment added by 121.45.42.17 (talk) 14:00, 5 August 2008 (UTC)

Another mistake: The RHS of this: B(x_1,y_1) B(x_2,y_2) = B(x_1 x_2 \pm ty_1 y_2,x_1 y_2 \pm y_1,x_2).\, has one too many comma's. Presumably it should be: B(x_1,y_1) B(x_2,y_2) = B(x_1 x_2 \pm ty_1 y_2,x_1 y_2 \pm y_1x_2).\, But I don't know for sure. —Preceding unsigned comment added by 121.45.160.125 (talk) 10:27, 14 August 2008 (UTC)
