Solving Triangles w/ Law of Sines & Cosines - [2-20-10]

More Lessons: http://www.MathAndScience.com Twitter: https://twitter.com/JasonGibsonMath In this lesson, you will learn how to use the law of sines and the law of cosines to solve triangles in trigonometry and precalculus. We will focus on the SSS (side-side-side) and SAS (side-angle-side) cases in which we first use law of sines, followed by using law of cosines, or vice versa. These problems are useful in many physics and engineering applications.
