Right Triangle Trigonometry (Wrap-Up)

Since most of class was just spent working on the specific problems, this wrap-up will be short ... just a couple of tips:

  • When finding the values of circular functions based on some initial information (like a point or some given values), drawing the respective "bowtie triangle" we saw in class helps make sure everything ends up in the right place.
  • When solving an application problem involving trigonometry, there are many possible paths to solve a given problem! Just be careful not to round things off too early or your answers might be a little bit off.

I've added the cofunction identities to our list of identities. Check back with that list every so often as we continue to work on it.
