### Modified 4.8 How to use trigonometry values to solve a word problem - Learn math online

http://www.freemathvideos.com In this video series I show you how to solve word problems using trigonometric functions such as sine, cosine, tangent and their inverses. When solving word problems with trigonometry it is important to set up a right triangle and determine the given values and the missing value(s) that you need to solve for. In this series we look at creating triangles by using bearings, angles of depression and elevation. In this tutorial I show you how to find the angle of elevation when given the opposite side and adjacent side of a triangle. We will use the inverse tangent function to find our answer. This math problem was filmed during live instruction for class. This is my way of providing a free online tutorial for students that want to learn math from an online tutor. Please visit my website where you can view all of my math lessons. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a live classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, finish your homework and get a better grade in your math class.
