Students will: graph sine and cosine functions; observe what happens as they change the value of a (amplitude) and b (frequency); learn how to calculate the period of a sine or cosine function. recognize, use, and represent algebraically patterns, relations, and functions; build new mathematical knowledge through problem solving; make and investigate mathematical conjectures
