Correctness in geometrical problem solving | Arithmetic and Geometry Math Foundations 40

Описание: The current technology for solving geometrical problems means that answers are typically in an approximate decimal form, and so strictly speaking incorrect. The problem arises with the reliance on angles, which are inherently imprecise.

This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics.

Screenshot PDFs for my videos are available at the website http://wildegg.com. These give you a concise overview of the contents of the lectures for various Playlists: great for review, study and summary.

My research papers can be found at my Research Gate page, at https://www.researchgate.net/profile/...

My blog is at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things.

Online courses will be developed at openlearning.com. The first one, already underway is Algebraic Calculus One at https://www.openlearning.com/courses/... Please join us for an exciting new approach to one of mathematics' most important subjects!
