Day 21 Agenda: DG11 --- 15 minutes Finish notes on Ellipse (U2 L3)

Lesson #3 (Part 2): Ellipse Accel Precalculus Unit #2: Algebra Topics Lesson #3 (Part 2): Ellipse EQ: How do you convert the equation of an ellipse to standard form?

C:(-1, 1) V:(-1,-3) (-1, 5) CV: (-4, 1) (2, 1) Example  Sketch the graph of the ellipse Identify all significant parts. C:(-1, 1) V:(-1,-3) (-1, 5) CV: (-4, 1) (2, 1)

In Class Practice: Sketch the graph for 9(x – 1)2 + 25(y + 2)2 = 225. Identify all significant parts. Sketch the graph for x2 + 4y2 + 6x – 8y = 3. Identify all significant parts. Sketch the graph for 4x2 + 9y2 – 16x + 18y = 11. Identify all significant parts.
