2/16/16 A Day at The Lab

     Today we used the computer lab for all three of my classes. My Precalc kids are really struggling with graphing sinusoidal functions. ie graphs of sine and cosine problems. The lab helped some but there was still much confusion at the end of class. I'm not sure how to break it down more for them. They seem to be lost at how to solve sine and cosine and way before getting to the graphs. Oh well, we have another day at it on Thursday. Hopefully some revelation will strike me by then.
