WebMay 1, 2024 · The key features of a parabola are its vertex, axis of symmetry, focus, directrix, and latus rectum (Figure 12.3.5 ). When given a standard equation for a parabola centered at the origin, we can easily identify the key features to graph the parabola. A line is said to be tangent to a curve if it intersects the curve at exactly one point.
WebStep - 1: Compare the equation of the parabola with the vertex form x = a (y - k) 2 + h and identify the values of h and k. By comparing x = 2 (y + 3) 2 + 5 with the above equation, … WebConic Sections: Parabola and Focus. example. Conic Sections: Ellipse with Foci
WebOct 31, 2024 · The distance between the vertex and the directrix (at the axis of symmetry) is always exactly the same as that between the vertex and the focus. 5 Focus: The focus … Web∵ axis of the parabola bisects the P Q and tangents drawn to the ends of the chord are perpendicular ∴ P Q is the latusrectum of the given parabola whose focus is (3 2, − 1 2). Hence tangents will intersect at (1, − 2) ∵ directrix is parallel to latusrectum ∴ Slope of directrix = slope of tangent at vertex = − 1 3 and Slope of ...
