New Trigonometry Method: Quadrance and Spread

In summary, the new trigonometry method of Quadrance and Spread is an alternative approach to traditional trigonometry developed by mathematician and physicist Norman Wildberger. It uses quadrance and spread instead of angles and sides, resulting in simpler and more generalized concepts. While it has many advantages, it may take some time to adjust to and has not yet been widely adopted. To learn more, there are online resources available and it may be helpful to have a solid understanding of traditional trigonometry before delving into the new method.

I haven't been here for a long time, so sorry if this was already posted:

Dr Norman Wildberger has devised a new method of trigonometry that gets rid of sin, cos, tan (and the like) functions and uses algebra instead. It's supposedly straight forward, more accurate in a lot of cases, and more consistant with basic math.

it uses properties called quadrance and spread.

Does anybody know anything about this? Is it credible?

1. What is the new trigonometry method of Quadrance and Spread?

The new trigonometry method of Quadrance and Spread is an alternative approach to traditional trigonometry, which uses the concepts of quadrance and spread instead of the traditional angle and side measurements. It was developed by mathematician and physicist Norman Wildberger as a way to simplify and unify trigonometric concepts.

2. How is the new method different from traditional trigonometry?

The main difference between the new method and traditional trigonometry is the use of quadrance and spread instead of angles and sides. Quadrance is a measure of the squared distance between two points, while spread is a measure of the squared ratio of two distances. This approach eliminates the need for trigonometric functions like sine, cosine, and tangent, and instead uses simpler algebraic equations.

3. What are the advantages of using Quadrance and Spread?

One of the main advantages of using Quadrance and Spread is its ability to simplify and generalize trigonometric concepts. This makes it easier to understand and apply in various mathematical and scientific problems. It also allows for more elegant and concise mathematical expressions, and can be extended to higher dimensions and non-Euclidean geometries.

4. Are there any limitations to the new method?

While the new method has many advantages, it also has some limitations. It may not be as intuitive for those who are used to traditional trigonometry, and it may take some time to adjust to the new concepts. It also has not yet been widely adopted, so there may be a lack of resources and support compared to traditional trigonometry.

5. How can I learn more about Quadrance and Spread?

There are many online resources available for learning about Quadrance and Spread, including videos, articles, and books by its creator Norman Wildberger. It may also be helpful to have a solid understanding of traditional trigonometry before delving into the new method. Additionally, practicing and solving problems using Quadrance and Spread will help in gaining a deeper understanding of the concepts.
