Web6 mrt. 2016 · The area of rectangle formed is A(θ) = 4abcosθsinθ = 2absin2θ. Maximum area is 2ab and it occurs when θ = π 4 (or when sin2θ is maximum). Your mistake is here A ′ (x) = 4(√b2 − b2x2 a2) + 1 2 × 4x((b2 − b2x2 a2) − 1 2 × − 2b2x a2). The mistake is in third step while differentiating.

WebFactor 4 4 out of 4x2 −16y2 4 x 2 - 16 y 2. Tap for more steps... 4(x2 − 4y2) 4 ( x 2 - 4 y 2) Rewrite 4y2 4 y 2 as (2y)2 ( 2 y) 2. 4(x2 − (2y)2) 4 ( x 2 - ( 2 y) 2) Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = x a = x and b = 2y b = 2 y. WebGiven the equation of an ellipse is 4x^2 + 16y^2 = 64. We need to find the center and foci. First we need to re-write the equation into the standard form of the ellipse. ==> x^2/a^2 … WebA: given equation: -x2=y2-25 Q: Find an equation for the ellipse whose graph is shown. y (8, 6) 16 A: Observe that from the given figure, it is an ellipse with a horizontal major axis, a=16 and a point… Q: Graph the ellipse 25x2 + 4y2 = 100 and locate the foci.
