Conic: A conic is defined as the locus of a point which moves such that its distance from a fixed point is always ‘e’ times its distance from a fixed straight line. Focus: The fixed point is called the focus of the conic. Directrix: The fixed straight line is called the directrix of the conic. Eccentricity: The constant ratio is called the eccentricity of the conic. General equation of a conic ax2 + 2hxy + by2 + 2gx + 2fy + c = 0 represents (i) a circle if a…

UNIT – I ANALYTICAL GEOMETRY 1.1 ANALYTICAL GEOMETRY I Straight Line: When a variable point moves in accordance with a geometrical law, the point will trace some curve. This curve is known as the locus of the variable point. If a relation in x and y represent a curve then (i) The co-ordinates of every point on the curve will satisfy the relation. (ii) Any point whose co-ordinates satisfy the relation will lie on the curve. Straight line is a locus of a point. https://clnk.in/qfwg Slope or gradient of a…
