What is the sine, cosine and tangent of 30 degrees?

0

Align the edge of the rule with 30 degrees on the altitude scale in the lower right corner of the back of the astrolabe. The alilade will form a triangle in the right hand shadow box. The triangle (and the box) are ten units wide. The height of the triangle is 6 while the hypotenuse is about 11.5. Using ratios of these numbers, we can calculate sine, cosine and tangent as indicated in the figure below.
