Unit Conversion_extra credit opportunity

This week we are really getting into the new stuff, actual Trig!

We have converted graphed angles in standard position and talked about what it means to be coterminal and convert from decimal degrees to degrees-minutes-seconds(3.1). 

Today (Monday) we learned how to convert degrees to radians and vice-versa.  It all boils down to a complete circle having 360-degrees and if we know the definition of a radian, a complete circle is 2pi radians.  And a more useful version is that every 180-degrees is equivalent to pi radians.

Extra credit opportunity:

For C-period, we did not define a radian clearly.  The first person from C-period to explain what a radian is in the comments section of this blog gets 10 credits of HW applied to Q1 or a free HW pass for next quarter.  I recommend going to www.khanacademy.org and searching "radian".  One of the videos should give a clear explanation.  Post a comment below with your definition and put your initials or name at the end of the comment.

For D-period, we did define radian.  So the first D-period student to state exactly how many radians comprise a full circle (to the nearest hundredth) you get the same extra credit deal.  Just state the number and put your initials or name in the comments section.

Quarter Ends Friday.  So we are pretty much done except what I am checking for HW and one short 3.1/3.2 quiz Thursday or Friday. 

If you are reading this and did not do the "function drawing" HW on the back of the jack o lantern sheet, that can be handed in by the end of the week as a HW credit to bring up you grade.
