What is the Quasilinear equation of an ellipse? In practice, I suddenly ask you to find the Quasilinear equation of an ellipse But it's not mentioned in the textbook I know the equation is x = plus or minus a ^ 2 / C But what is the so-called guide line drawn on the graph? What does it represent? I'm very unfamiliar with it, and I'll write down how much about it

Excimer equation [edit this paragraph] definition of excimer for elliptic equation (focus on X-axis as an example) x ^ 2 / A ^ 2 + y ^ 2 / b ^ 2 = 1 (a > b > 0 a is the semi major axis, B is the semi minor axis, C is half of the focal length) x = a ^ 2 / C x = - A ^ 2 / C for hyperbolic equation (focus on X-axis as an example) x ^ 2 / A ^ 2-y ^ 2 / b ^ 2 =



What is the general equation of an ellipse


Ax^2+By^2+Cxy+Dx+Ey+F=0



How to solve elliptic general equation
Given the coordinates P (x0, Y0) of the center of the ellipse, the ratio H of the major axis to the minor axis and an endpoint P1 (x1, Y1) relative to the major axis of the center of the ellipse, how to find the general equation of the ellipse
No, you give the standard equation. If there is an angle alpha between the long axis and the X axis, how can we find it


Let a = b * h, (half axis length)
b=|y1-y0|
a=h*|y1-y0|
Then the elliptic equation (x-x0) ^ 2 / [h * | y1-y0 |] ^ 2 + (y-y0) ^ 2 / (y1-y0) ^ 2 = 1



It is known that the square sum of the two real roots of the quadratic equation x 2-m x + 2m-1 = 0 is 23, and the value of M is obtained


Let the two real roots of the quadratic equation x2-mx + 2m-1 = 0 be X1 and X2 respectively, then: X1 + x2 = m, x1 · x2 = 2m-1, ∵ the sum of the squares of the two real roots of the quadratic equation x2-mx + 2m-1 = 0 is 23, ∵ X12 + X22 = (x1 + x2) 2-2x1 · x2 = M2-2 (2m-1) = m2-4m + 2 = 23
