Law of Cosines

The video tutorial explains how to solve a problem involving two boats traveling at different speeds and forming a 110-degree angle. The goal is to find the distance between the boats after 30 minutes. The instructor discusses the use of vectors and triangles, ultimately deciding to apply the law of cosines. The problem is broken down into steps, including converting speeds to distances for 30 minutes and performing calculations using the law of cosines. The instructor emphasizes the importance of ensuring the calculator is set to degrees and verifies the solution through calculations.
