Formula for the latus rectum of a parabola?

The formula for the Latus rectum is simply 2L = 4a with a stands for the distance of the focus from the vertex of the parabola. Given a, you can simply solve for the length of the latus rectum by using this formula.. L = 2a

Its latus rectum is its diameter. Since there are infinitely many diameters, the question needs to be more specific.


How was the term latus rectum created?

The word latus rectum came from Latin, latus means 'side' or line and rectum means 'straight'.

What is the latus rectum for 6y squared plus 24y plus 25?

The question is incomplete because it is not an equation. Assume that the expression given equals x, i.e.: 6*y^2+24*y+25=x. Completing the square on y: 6*[y^2 + 4*y + (+4/2)^2 - (+4/2)^2] + 25 = x, 6*[(y+2)^2 - 4] + 25 = x, 6*(y+2)^2 - 24 + 25 = x, 6*(y+2)^2 = x-1, and (y+2)^2 = (1/6)*(x-1). This is a translated parabola with y=-2 its axis of symmetry and (1,-2) its vertex. The domain of the parabola is x >= 1 and the range is that y can be any real number. If the distance from the vertex to the focus along the axis of symmetry is called p, then, from the equation, 4*p = 1/6 and p = 1/24. That puts the focus at (1+1/24,-2) and the directrix at x = 1-1/24. The length of the line segment called the latus rectum is |4*p| = 1/6 with endpoints (1+1/24,-2+1/12) and (1+1/24,-2-1/12). The vertex and the endpoints of the latus rectum are points on the parabola and, in conjunction with the domain and range, are used to sketch the parabola. BTW, "latus" and "rectum" are latin for "side" and "to lead in a straight-line or in the right direction" (the human large intestine's last, and straight, section is also called the "rectum").


What does the root word latus mean?
