Wednesday, January 12th

• Pre-Calculus: We graded p. 474, I collected the trig graphs assigned Monday, and I started to give notes on sine and cosine graphs
• Statistics: We graded section 6.1...and then we worked on case study and assigned p. 300;1-10,12-24x3s
• Algebra 1B...p. 528-18-29 all...find the vertex only
