WebMar 28, 2024 · We were asked to find the product of the parameters(t) of the point cut by the circle on the parabola (other than the extremities of the focal chord).Doing some algebra we obtain this product as 3,but I feel that the parameters would be imaginary since I don't think that such a circle can exist.Am I correct? Webchord, 4p . This chord may be used to help graph the parabola by determining two points on it. Example 2: Write the standard form of the equation of the parabola with a vertex at the origin and focus at (2, 0). Graph the parabola, including the directrix, the primary focal chord as well as the two points on the graph that they determine. Solution:
How to find the equation of common chord between a circle and a parabola?
WebApr 6, 2024 · Substitute the value you get in the expression of length of focal chord ‘c’ and get the value of c. Complete step-by-step answer: We have been given the equation of parabola as ${{y}^{2}}=4ax$ . We need to find the focal chord of the parabola at a distance p from the vertex. Let us take 2 points on the parabola as P and Q. Web∴ Equation of focal chord is ... The length of a focal chord of the parabola y 2 = 4 a x making an angle with the axis of the parabola is. Medium.

WebIit Jee Important Formula May 13th, 2024 - JEE Main Result 2024 will be Declared Today likely at 11 00 AM as per few reports for the online and offline JEE Main entrance exam held on April 8th 15th and 16th Focal chord of Parabola Study Material for IIT JEE May 13th, 2024 - Grasp the concepts of focal chord of a parabola including parabola equation WebNote: If the chord joining the points t1 and t2 on the parabola y2 = 4ax is a focal chord then t1t2 = –1. Proof: Equation of the parabola is y2 = 4ax Focus S = (a, o) The equation of the chord is y(t1 + t2) = 2x + 2at1t2 If this is a focal chord then it passes through the focus (a, 0). ∴ 0 = 2a + 2at1t2 ⇒ t1t2 = –1. 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 ... how to sear cod fillet
