No homework tonight...which means it's a great opportunity to start studying for Friday's quiz!
You will need to know how to graph sine and cosine with vertical shifts, changes in amplitude, reflections, and changes to period. Also, we'll need to write equations of trig functions given the graph. So to study, look back at the homework from Monday night--this is the stuff you need to know how to do!
See you all tomorrow for some graphs of tangent!
Two more days of hard work until April vacation!
