Trigonometry revealed in ancient Babylonian tablet



As a good point to note is what you know is not true!
Always ask how or why it is. Ask, people never ask!
Always learn because you never know where that road is talking you.
Why is it talking you somewhere? Boom that is he point!

Ask and find out because everything you know is not true!
As in the Babylonian tablet a better way was found vs today in Trigonometry!

~~~~~World's first trigonometry revealed in ancient Babylonian tablet
Aug. 25 (UPI) -- The ancient Babylonians - who lived from about 4,000 BCE in what is now Iraq - had a long forgotten understanding of right-angled triangles that was much simpler and more accurate than the conventional trigonometry we are taught in schools.

Our new research, published in Historia Mathematica, shows that the Babylonians were able to construct a trigonometric table using only the exact ratios of sides of a right-angled triangle. This is a completely different form of trigonometry that does not need the familiar modern concept of angles.

At school we are told that the shape of a right-angled triangle depends upon the other two angles. The angle is related to the circumference of a circle, which is divided into 360 parts or degrees. This angle is then used to describe the ratios of the sides of the right-angled triangle through sin, cos and tan.

But circles and right-angled triangles are very different, and the price of having simple values for the angle is borne by the ratios, which are very complicated and must be approximated.
