= =  **Law Of Sine & Cosine** media type="file" key="Movie on 3-4-12 at 1.36 PM.mov" align="left" width="254" height="254" ** Hey everyone! Welcome to our Pre-Calc Project. These webpages will not only show how we got our work & give examples, but will also provide audio and videos for a better understanding of the way that Law of Sine & Law Of Cosine works. As stated before, the Law Of Sine and Law Of Cosine aren't only used for math classes. These Laws can be correlated to the real world. ** ** For better clarification, if you are given two mountains and want to know which one is the tallest you can use either Law Of Sine or Law Of Cosine. For one of the mountains, given two angles and one side you can use the equation for Sine you can find the other lengths or even Law of Cosine. If you are given a length that corresponds to an angle and another extra side you can use Law Of Sine. If not, you can use Law of Cosine to find the missing information. Finding all the missing information will lead you to which mountain is the largest. **  **//Engineers and construction workers are people who need to use or can use these laws as well. If you need to know how tall a building is from the angle you are standing at and are given the length that you are standing away from it, given that one of them is a ninety degree angle as well you can add both angles and subtract them from 180 to find the missing angle. From knowing this missing information you can find the length by using Law Of Sine.//**
