ADVANCED MATHEMATICS II (SECONDARY) SELECTIVE UNIT 4 (S04) (Conics (11.1-11.5)) (July 2013) Unit Statement: The student will be introduced to the graphs and equations for the four conic sections: circle, ellipse, parabola and hyperbola. This selective unit is beneficial for the student with interests in architecture and engineering, particularly optical engineering, due to conics’ many real world applications. Essential Outcomes: (must be assessed for mastery) 1. The Student Will define parabolas, circles, ellipses and hyperbolas geometrically. [11.1-11.3, pp. 724-741] 2. TSW use the parameters of a parabola (focus, directrix) to graph a parabola with both a horizontal axis and vertical axis. [11.1 pp. 724] 3. TSW graph an ellipse given an equation by identifying the major axis, minor axis and foci. [11.2, pp. 732] 4. TSW define eccentricity and find the equation of an ellipse from its eccentricity and foci. [11.2, pp. 732] 5. TSW graph a hyperbola given an equation by identifying vertices, transverse axis, asymptotes and foci. [11.3, pp. 741] 6. TSW write equations of parabolas, ellipses and hyperbolas given an original equation and a description of an applied horizontal or vertical shift. [11.4, pp. 750] 7. TSW sketch graphs of parabolas, ellipses and hyperbolas that have been shifted horizontally and/or vertically. [11.4, pp. 750] 8. TSW determine if a conic in the form Ax2+Cy2+Dx+Ey+F=0 based on the values of A and C. [11.4, pp. 750] a. If A or C is zero, the conic is a parabola. b. If A=C, the conic is a circle. c. If A and C have the same sign and A ≠B, the conic is an ellipse. d. If A and C have opposite signs, the conic is a hyperbola. e. If A and C both equal zero, it is a degenerate conic. 9. TSW graph a rotated conic. [11.5, pp. 757] 10. TSW identify a conic of the form Ax2+Cy2+Dx+Ey+F=0 by the discriminant B2-4AC. [11.5, pp. 757] a. If the discriminant is zero, the conic is a parabola. b. If the discriminant is less than zero, the conic is an ellipse. c. If the discriminant is more than zero, the conic is a hyperbola.

The teacher’s discretion on the student’s holistic performance on the unit, including such items as: the above ‘A’ level rubric, the unit project, group work and class discussions will determine ‘A’ level mastery. TSW 1. TSW define parabolas, ellipses and hyperbolas geometrically. 2. TSW use the parameters of a parabola (focus, directrix) to graph a parabolas with both a horizontal axis and vertical axis. 3. TSW graph an ellipse from an equation by identifying the major axis, minor axis and foci. 4. ‘A’* LEVEL TSW use the geometric definition of one (or more) parabolas to create equations of parabolas. TSW compare, analyze and draw conclusions on families of parabolas with varying parameters (focus, directrix).
