Algebra 2/Trig 5/16-5/20/16 Mon Block 1, 3, 5 (CAASP ELA) 10.1b Parabola: (x – h)2 = 4p(y – k) (vert) (y – k)2 = 4p(x – h) (horiz) Explain: Vertex, Focus, Directrix, p (Use Parabola Handout) Exs: Graph (y – 5)2 = –2(x + 3) Ex: Write eqn. with vertex at origin, focus at (0, –6) (Draw a picture) General Form to Standard Form Ex: x2 + 2x + 2y – 1 = 0 by Completing the Square Since Block, start to go over some problems last part of class (keep track so as not to repeat on next class) Tue Wed Thu Fri HW: P 783: 64, 67, 70, 71-74, 76, 85, 87, 89 Block 2, 4, 6 (CAASP ELA) Same plans as Monday HW: Same as Monday 10.2a Ellipses: Explain defn. (sum of distances to foci) Use ellipse handout to explain equations, vertices, foci, major/minor axes and c2 = a2 – b2 (vertical/horiz depends on where a is) Ex: Find ellipse w/ major axis 10, foci at (4,7) and (-2, 7) (Draw a picture) Ex: 4(x – 3)2 + (y + 4)2 = 36 Graph, find foci HW: P 792: 10-27 E.O.P Block 1, 3, 5 (CAASP ELA) 10.2b Ellipses into standard form Ex: x2 + 4y2 + 6x – 8y + 9 = 0 Why not a circle? Convert. Mention eccentricity e = c/a. Look at pictures pg. 791 Since Block, start to go over some problems last part of class (keep track so as not to repeat on next class) HW: P 793: 29, 31, 35-42 (part (a) only) Block 2, 4, 6 (CAASP ELA) Same plans as Thursday HW: Same as Thursday
