Went over homework on more limits, then took first limits assessment. Worked on handout on infinite limits for remainder of class.
Homework:
Finish front side (#1-12) of infinite limits handout [F-L1b]

I was not in due to an important family matter. Students worked on ACT practice problems.
Passed back tests, went over how to use Powerschool to see what homework is required for reassessing and how grading system works. Went over limits that produce infinity homework worksheet front side (answers are linked on Monday's post). Introduced concept of indeterminate forms, and how if you get one of them when using direct substitution on a limit that means you should be able to extract an a numerical answer through factoring, cancelling, or similar means.
Introduced the squeeze theorem and how it leads to the 2 special trig limits, involving sine and cosine. Did an example, another example will be linked in the resources below. Quickly introduced definitions of vertical and horizontal asymptotes as defined by limits, more on this coming Monday.
