Maths is Fun

I was just searching on net the value of cos 30 and I came across a very informative website. They had displayed a easy way of remembering sine/cosine values.

sin 0° = sqrt(0)/2
sin 30° = sqrt(1)/2
sin 45° = sqrt(2)/2
sin 60° = sqrt(3)/2
sin 90° = sqrt(4)/2

cos 0° = sqrt(4)/2
cos 30° = sqrt(3)/2
cos 45° = sqrt(2)/2
cos 60° = sqrt(1)/2
cos 90° = sqrt(0)/2

The website http://www.mathisfunforum.com contain other interesting Mathematics games , puzzles too.
