Graphing Sine and Cosine Functions Assessment
Overview
This assessment is used to check for understanding of standard NC.M4.AF.2.3 The assessment is open-ended and asks for students to provide understanding of amplitude, period, phase shift and vertical shift of sine and cosine graphs. It also assesses writing equations of sine and cosine and sketching their graphs.
