How to solve directrix
WebJan 1, 2016 · The directrix is the vertical line x = a2 c. Explanation: For a hyperbola (x − h)2 a2 − (y −k)2 b2 = 1, where a2 +b2 = c2, the directrix is the line x = a2 c. Answer link WebWe can use this equation to represent the distance from a random point on the parabola (x, y) to the focus and directrix. Let's say that the focus of this parabola is point (a, b). Let's say that the directrix is line y = t. The distance of the x coordinate of the point on the parabola …

Did you know?
WebApr 4, 2024 · The directrix is the line which is parallel to y axis and is given by x = a e or a 2 c and here e = a 2 + b 2 a 2 and represents the eccentricity of the hyperbola. This can be made clear with an example: Let us have the hyperbola where we have x 2 16 − y 2 9 = 1 So we can compare this above equation with x 2 a 2 − y 2 b 2 = 1 and we will get: WebGraph the parabola with a horizontal directrix, then place another sheet of paper over your work, draw in your coordinate grid, and plot the line you want to use for your new …
