Have you ever heard that you can watch the sunset twice by riding a really tall elevator? Or driving up a mountain? Or simply by laying down and then standing back up? In this video we tackle how theoretically plausible these scenarios are with math! All you need is a little geometry and trigonometry to find out how to watch a double sunset

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.
