Exact Values

Thursday, September 17, 2009

Exact values is just a really technical term for a value at a specific, given location. The trick to these is to first evaluate where on the unit circle the angle is. We can do this by just remembering what we learned about the unit circle in previous lesson, and just expand our thinking just a bit. for example: 17pi/4 looks impossible, but if you think that pi can be didided into 4 and a inverse fraction is possible because we are more than only one pi. Once i can grasp that principal i had no problems when working my way through lesson 3. An exact value, if refering to a unit circle, is just a coordinate on a plane, and depeinding if you are asked to find the Sin Cos or Tan, the coordinates will always follow a type of pattern (as i found from working on the chart we were asked to make).
