Lesson Plans for the Week of February 12, 2018

For Tuesday:

Watch this video on how to graph secant and cosecant (up to about minute 5:15). Try the worksheet below. I’ll be back to tomorrow to make sure you can do tan, cot, sec, and csc. Then we will practice practice practice before our next test (not scheduled yet).

graphing secant and cosecant

hint: rewrite each problem as either a sine or cosine, graph the sine/cosine then draw in the cosecant/secant graph. This is why you needed to know sine and cosine so well! It’s like getting a “four for two” bargain!
