Initial Post: Sine, cosine and tangent are foundational for what we will be learning for the rest of the class, so lets take some time this week to ensure we understand what they are and how to find and/or use them. Part 1: Before using a new math concept it is good to understand what it actually means, so choose one of those terms and find the definition. What does the root of each word mean? Now dont just give a dictionary definition. Do a little research and include at least one thing you found on the history of the word that you found interesting in your own words. Part 2: Next, lets make sure we know how to use these functions. Post a right triangle with all of the sides given (or make one up but remember the sides must work with the Pythagorean theorem) and then choose one angle to label as unknown. Then, set up the ratios for each trig function for the labeled angle
