ResearchFlatMoon | Understanding Sin/Cos/Tan @ResearchFlatMoon | Uploaded July 2021 | Updated October 2024, 7 hours ago.
Introducing a new series from Bob the Science Guy/ResearchFlatMoon- Mathematics Explains the Universe | Part 1 Sin/Cos/Tan. We introduce the basic trig functions and show how they are found in acute angles of triangles and on the unit circle. We look at how to determine the rotational speed of the earth at any latitude and how much 'drop' there is over a given distance, comparing it to 8 inches/mile^2.
I did make two slight errors, once I was talking about circumference and accidently said 'diameter'. The other was an error I made on the 8 inch per mile squared section. The correct calculation is in the video, but there is an incorrect number which wasn't mentioned but can be seen on the board (45.45). Just ignore that.
In future episodes we will look at the curve calculator, Al Biruni and the Radius of the Earth, Great Circles and the mathematics the Ancient Greeks used to determine the sizes of the Earth, Moon and Sun and the distances between them.
