 # CONIC SECTIONS: PARABOLA,ELLIPSE AND HYPERBOLA (CONT)

THE HYPERBOLA

The hyperbola is the locus of a point P, moving in a plane such that the distance from two fixed points called the foci have a constant difference

GENERAL EVALUATION

1.  Write the equation of the ellipse,  x2 + 3y2 + 2x –24y + 46 = 0 in the canonical form hence determine. Its vertices and foci

2.  Find the vertices and foci of the hyperbola  25x2 – 4y2 = 100

3.  Find the equation of the tangent and normal to the parabola y2 – 18x = 0 at point (2,6)
