Purpose of use
To calculate the viewing angle for mounting a large screen TV above my fireplace. I used the distance (in inches ) from my sitting position to the wall and the distance (in inches) above eye-level to the proposed center of the TV screen. Moving the TV up or down a little changed the viewing angle from around 11% (acceptable) to almost 20% (too high),

Purpose of use
Calculate pi with the Archimedes polygon method (100,000,000-sided inscribed polygon)
Used: hypotenuse and angle
hypotenuse = 1
Angle = 180/ 100,000,000 = .0000018
(Solve for height h)
height h = 3.1415926535898E-8
height h * 100,000,000 = 3.1415926535898

Stringer
Comment/Request
Since I'm cutting stair stringers it could've helpful to put the hypothoesese measurements into tape measure fractions so mine was 29.702693... I believe that should be about 29 11/16 5/8 or 3/4 would serve for my purpose but I know a lot of guys who would go throu hell converting 29.7. If you really wanted to go above the mark a riser/landing calculator would help
