1 = √[1] = √[(-1) * (-1)] = √[-1] * √[-1] = i * i = iČ = -1. Thus, 1 = -1. QED

Numbers are so much fun. I used to absolutely pi** off my math teachers in school with dumb stuff like this.

O_o

Given point P and location L, create the look at, up, and right vectors of a camera's orientation matrix that is located at L and looking at point P. You can use Z as up, or whatever you want, just tell me which you're using.

Oh, and please show your work.

1/11=.0909090~~~

3/11=.2727272727~~~
10/11=.90909090~~~~
11/11=.99999999~~~ = 1

You are essentially adding .0909090909~~~ for every eleventh you add to the fraction. At the very end you get .99999~~~ or 11/11 (the real number) which we all know as 1 therefore .9999~~~=1.
