Unit 8, Activity 4, Polar Equations of Conics Blackline Masters, Advanced Math – Pre-Calculus Page Louisiana Comprehensive Curriculum, Revised 2008 259 The equations below are those of conics having a focus at the pole. In each problem (a) find the eccentricity; (b) identify the conic; (c) describe the position of the conic and (d) write an equation of the directrix which corresponds to the focus at the pole. Graph the conic. Verify your answers by graphing the polar conic and the directrix on the same screen. 1. r =
