= (2a 2 / b) Some Important Conclusions on Conjugate Hyperbola (a) If are eccentricities of the hyperbola & its conjugate, the (1 / e 1 2) + (1 / e 2 2) = 1 (b) The foci of a hyperbola & its conjugate are concyclic & form the vertices of a square. a = semi-transverse axis. When given the coordinates of the foci and vertices of a hyperbola, we can write the equation of the hyperbola in standard form. Like hyperbolas centered at the origin, hyperbolas centered at a point $$(h,k)$$ have vertices, co-vertices, and foci that are related by the equation $$c^2=a^2+b^2$$. See . The vertices are some fixed distance a from the center. (This means that a < c for The center is midway between the two vertices, so (h, k) = (–2, 7). A hyperbola is the set of all points in a plane such that the difference of the distances between and the foci is a positive constant. The standard form of a hyperbola can be used to locate its vertices and foci. Vertices: Vertices: (0,±b) L.R. Ex 11.4, 14 Find the equation of the hyperbola satisfying the given conditions: Vertices (±7, 0), e = 4/3 Here, the vertices are on the x-axis. Step 1 : Convert the equation in the standard form of the hyperbola. Also, the line through the center and perpendicular to the transverse axis is known as the conjugate axis. b = semi-conjugate axis. The "foci" of an hyperbola are "inside" each branch, and each focus is located some fixed distance c from the center. The standard form of a hyperbola can be used to locate its vertices and foci. The foci lie on the line that contains the transverse axis. Horizontal "a" is the number in the denominator of the positive term. The line going from one vertex, through the center, and ending at the other vertex is called the "transverse" axis. The conjugate axis is perpendicular to the transverse axis and has the co-vertices as its endpoints. The co-vertices of the hyperbola are {eq}(h, k \pm b) {/eq} We are writing the steps to find the co-vertices of a hyperbola. A hyperbola is the set of all points in a plane such that the difference of the distances between and the foci is a positive constant. See . The vertices are above and below each other, so the center, foci, and vertices lie on a vertical line paralleling the y-axis. The foci of the hyperbola are away from its center and vertices. Hyperbolas: Standard Form. The transverse axis is a line segment that passes through the center of the hyperbola and has vertices as its endpoints. We can use this relationship along with the midpoint and distance formulas to find the standard equation of a hyperbola when the vertices … When given the coordinates of the foci and vertices of a hyperbola, we can write the equation of the hyperbola in standard form. center: (h, k) vertices: (h + a, k), (h - a, k) c = distance from the center to each focus along the transverse axis. Therefore, the equation of the hyperbola is of the form / – / = 1 Now, coor#dinates of vertices are (± a,0) & Given vertices = (±7, 0 If the x-term is positive, then the hyperbola is horizontal. Then the a 2 will go with the y part of the hyperbola equation, and the x part will be subtracted. (c) 2 hyperbolas are similar if they have the same eccentricities.
