Section 10.1 & 10.2: Distance & Midpoint Formulas, Equations of Cirlces PreCalculus March 14, 2016 Chapter 10: Conic Sections Conic Section - 2D shape that is created when you cut a double right cone with a plane. A B Distance Formula d= √ (x 2 x 1 ) 2 + (y 2 y 1 ) 2 *based on the Pythagorean theorem *c 2 =a 2 +b 2 , thus c = √ a 2 +b 2 * a = (x 2 x 1 ) and b = (y 2 y 1 ) (x 2, y 2 ) (x 1, y 1 ) y 2 y 1 x 2 x 1
