Here, you will learn what is rectangular hyperbola and parametric equation of rectangular hyperbola with example.<\/p>\n
Let’s begin –<\/p>\n
The particular kind of the hyperbola in which the length of it’s transverse axis and conjugate axis are equal is called rectangular hyperbola. The eccentricity of the rectangular hyperbola<\/strong> is \\(\\sqrt{2}\\) and the length of it’s latus rectum is equal to it’s transverse axis or conjugate axis.<\/p>\n The equation of rectangular hyperbola is xy = \\(c^2\\).<\/p>\n<\/blockquote>\n The Rectangular hyperbola referred to its asymptotes as axis of coordinates.<\/p>\n The parametric equation of the rectangular hyperbola xy = \\(c^2\\) with parametric representation is x = ct, y = c\/t, t \\(\\in\\) R – {0}.<\/p>\n<\/blockquote>\n For the hyperbola, xy = \\(c^2\\)<\/p>\n (i) Vertices : (c, c) & (-c, -c).<\/p>\n (ii) Foci : (\\(\\sqrt{2c}, \\sqrt{2c}\\)) & (\\(-\\sqrt{2c}, -\\sqrt{2c}\\))<\/p>\n (iii) Directrices : x + y = \\(\\pm \\sqrt{2c}\\)<\/p>\n (iv) Latus rectum : l = \\(2\\sqrt{2c}\\) = T.A = C.A<\/p>\n<\/blockquote>\n Note :<\/strong><\/p>\n (a) The equation of chord joining the points \\(P(t_1)\\) & \\(Q(t_2)\\) is x + \\(t_1t_2\\)y = c(\\(t_1+t_2\\)) with slope, (b) The equation of the tangent to rectangular hyperbola in point form at P(\\(x_1, y_1\\)) is \\(x\\over x_1\\) + \\(y\\over y_1\\) = 2 & in parametric form at P(t) is \\(x\\over t\\) + ty = 2c.<\/p>\n (c) Equation of normal in parametric form is y – \\(c\\over t\\) = \\(t^2\\)(x – ct).<\/p>\n (d) The equation of chord with a given middle point as (h, k) is kx + hy = 2hk.<\/p>\n\n\n Example : <\/span> Find the parametric representation and equation of tangent at the point (1, 2) to the rectangular hyperbola xy = 2.<\/p>\n Solution : <\/span>Since, the equation of rectangular hyperbola is xy = 2. Hope you learnt what is the equation of rectangular hyperbola, learn more concepts of hyperbola and practice more questions to get ahead in the competition. Good luck!<\/p>\n\n\n\n
Parametric Equation of Rectangular Hyperbola<\/h2>\n
\n
Basic Definitions of Rectangular Hyperbola :<\/h2>\n
\n
m = \\(-1\\over t_1t_2\\).<\/p>\n
\nComparing with the equation of rectangular hyperbola xy = \\(c^2\\).
\nwe get c = \\(\\sqrt{2}\\)
\nEquation in parametric representation x = ct and y = c\/t.
\n\\(\\implies\\) x = \\(\\sqrt{2}\\)t and y = \\(\\sqrt{2}\\)\/t
\nEquation of the tangent to rectangular hyperbola in point form at P(\\(x_1, y_1\\)) is \\(x\\over x_1\\) + \\(y\\over y_1\\) = 2
\n\\(\\implies\\) \\(x\\over 1\\) + \\(y\\over 2\\) = 2
