Different Types of Ellipse Equations and Graph<\/a><\/p>\nExample<\/strong><\/span> : For the given ellipses, find the length of latus rectum.<\/p>\n(i) \\(16x^2 + 25y^2\\) = 400<\/p>\n
(ii) \\(x^2 + 4y^2 – 2x\\) = 0<\/p>\n
Solution<\/strong><\/span> :<\/p>\n(i)<\/strong> We have,<\/p>\n\\(16x^2 + 25y^2\\) = 400 \\(\\implies\\) \\(x^2\\over 25\\) + \\(y^2\\over 16\\),<\/p>\n
where \\(a^2\\) = 25 and \\(b^2\\) = 16 i.e. a = 5 and b = 4<\/p>\n
Clearly a > b,<\/p>\n
Therefore, Length of the Latus Rectum (L) = \\(2b^2\\over a\\)<\/p>\n
\\(\\implies\\) L = \\(2\\times 16\\over 5\\) = \\(32\\over 5\\)<\/p>\n
(ii) <\/strong>We have,<\/p>\n\\(x^2 + 4y^2 – 2x\\) = 0<\/p>\n
\\(\\implies\\) \\((x – 1)^2\\) + 4\\((y – 0)^2\\) = 1<\/p>\n
\\(\\implies\\) \\((x – 1)^2\\over 1^2\\) + \\((y – 0)^2\\over (1\/2)^2\\) = 1<\/p>\n
Here, a = 1 and b = 1\/2<\/p>\n
Clearly a > b,<\/p>\n
Therefore, Length of the Latus Rectum (L) = \\(2b^2\\over a\\)<\/p>\n
\\(\\implies\\) L = \\(2\\times 1\/4\\over 1\\) = \\(1\\over 2\\)<\/p>\n
Note<\/strong> : For the ellipse \\((x – h)^2\\over a^2\\) + \\((y – k)^2\\over b^2\\) = 1 with center (h. k),<\/p>\n(i)<\/strong> For ellipse a > b,<\/p>\nThe equation of latus rectum is x = \\(\\pm ae + h\\).<\/p><\/blockquote>\n
(ii)<\/strong> For ellipse a < b,<\/p>\nThe equation of latus rectum is y = \\(\\pm be + k\\).<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
