We should recognise this as a circle of radius 5 centred on the origin. Differentiating Implicitly wrt x we get: 2x +2y dy dx = 0. ∴ y dy dx = − x. ∴ …

Web17 sep. 2024 · You have to find out which one is the correct one (because the circle has two points where x = 4) The best thing here is implicit differentiation, so take dy/dx of both sides to get: 2x + 2y* (dy/dx) = 0 2y* (dy/dx) = -2x dy/dx = -x/y d^2y/dx^2 = - (y – x* (dy/dx)) / y^2 dy/dx (4,3) = -4/3 Web2 dec. 2024 · Find an answer to your question If (x 2y)dy/dx=2x-y what is the value of. The second differential of the function is 3/7. Given the differential function. Differentiate both sides with respect to x implicitly. Get the first derivative at the point (3, 0). Substitute into the second derivative to have:. Hence the second differential of the function is 3/7 ... hgbu meaning

Web9 dec. 2013 · If x^2=25-y^2, what is the value of [ (d^2) (y)]/ (dx^2) at the point (3,4)? asked by Lindsay December 9, 2013 1 answer 2x = -2y dy/dx dy/dx = -x/y at (3,4) dy/dx = -3/4 differentiate again, 2 = -2y (d^2 y/dx^2) + (dy/dx) (-2dy/dx) 2 = -2y (d^2 y/dx^2) - 2 (dy/dx)^2 2 = -2 (4) (d^2 y/dx^2) - 2 (9/16) (d^2 y/dx^2) = (2 + 9/8)/-8 = -25/64 or WebSimilarly, x 2 +y 2 =25 can define y as a function of x if you make a choice of sign for y, either y=+sqrt (25-x 2) or y=-sqrt (25-x 2 ). It's a subtle but important distinction between functions, equations or formulas which define them, and also their graphs (which is what the circle here is). 5 [deleted] • 7 yr. ago WebIf d 2 y/dx 2 = 0, you must test the values of dy/dx either side of the stationary point, as before in the stationary points section. Example. Find the stationary points on the curve y = x 3 - 27x and determine the nature of the points: At stationary points, dy/dx = 0 dy/dx = 3x 2 - 27. If this is equal to zero, 3x 2 - 27 = 0 Hence x 2 - 9 = 0 ... hg. butzko
