WebConic Sections 2,009 Solved Examples Example 1: Find the equation of a conic whose focus is at (1, 0) and whose directrix is 2x + 5y + 1 = 0. Also, e = 1/ √2. Solution: 1 2 = ( h − 1) 2 + k 2 12 h + 5 k + 11 29 12 x + 5 y + 11 58 = ( x − 1) 2 + y 2 Squaring both sides, we get 4x 2 + 25y 2 + 1 + 20xy + 10y + 4x Which is the required equation. WebThe general equation of any conic section is a second order, non-homogeneous equation in x and y: a x 2 + b x y + c y 2 + d x + e y + f = 0. Depending on the restrictions applied …
