Applied Linear Algebra (part5) Using Linear Algebra in 4 Dimensions

You might think building a simple wooden pyramid is easy. But turns out carpentry involves a lot of math! Each face is an equilateral triangle, so you’d expect to tilt the saw blade at 30 degrees... but that’s completely wrong! So how do you find the right angle? Well, that will involve some geometry and trigonometry, but for the simplest solution we'll use linear algebra in 4 dimensions!

Math The World is dedicated to bringing real world math problems into the classroom and answering the age old question “when will I ever use this?”

We use unique topics for algebra, trigonometry, calculus, and much more and go beyond context problems and use a technique called mathematical modeling to find solutions to real world questions and real world problems. These videos are great for students who plan to enter technical fields that require real world problem solving, and can be a great resource for teachers looking for ways to bring real world contexts into their classroom.
