First define the sine as the ratio of the lengths of the opposite side and the hypotenuse in a right triangle. (You can do it in a unit circle too, which works out the same.) Now consider a triangle with two 45° angles and, for simplicity, sides of length 1: By the Pythagorean T...

it just considers the angular size of focal plane that the eyepiece is magnifying which depends on the focal length of the scope and the diameter of the field stop. It's an isosceles triangle whose base is the field stop and whose height is the...

The curved paths of the electrons are drawn through the calculated intermediate structures (start: triangle, end: square) Full size image The wavefunction tile interpretation clearly supports the homolytic mechanism put forward by valence-bond calculations. Furthermore, recovering this from MO ...
sheet position in the booklet to cut length280. For example, the difference in lengths between sheets can be smaller using spine shape810than using spine shape820, because when using spine shape820, the outer sheets have to travel two sides of a triangle instead of (approximately) its ...
