The first directrix is x = h - \frac {a^ {2}} {c} = - \frac {9 \sqrt {5}} {5} x = h ca2 = 59 5. succeed. So the best option to get rid of the radical sign is to square it, which you must do on both sides of the equation to not change its values. From the source of Pauls online Notes: Parabolas, Sketching Parabolas, Axis direction. WebWrite the equation of the parabola Given the directrix y = 2 and focus (0, 8) find: The vertex. You're gonna get an Web2 In general, if we have ( y n) 2 = 4 p ( x m), then the vertex is ( m, n), the axis of symmetry is y = m, the focus is ( p + m, n), the directrix is x = m p. Hence, for your case, you'll have p + m = 10, n = 0, m p = 4 n = 0, m = 3, p = 7. Well, we just apply the distance formula, or really, just the Pythagorean Theorem. Furthermore, the Directrix of a parabola can also be calculated by a simple equation that is: y = c \frac { (b + 1)} { (4a)} . How Parabola Calculator Works? Parabola equation calculator makes the calculation faster and error-free as it uses the maths parabola equation. To get convenience, you need to follow these steps: If we consider only parabolas that open upwards or downwards, then the directrix will be a horizontal line of the form y = c . Given the focus and the directrix of a parabola, we can find the parabola's equation.
