Q. If xy3+yx2=0 -x y^{3}+y-x^{2}=0 then find dydx \frac{d y}{d x} in terms of x x and y y .\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Differentiate terms: To find the derivative dydx\frac{dy}{dx}, we need to differentiate the given equation with respect to xx, treating yy as a function of xx (implicit differentiation).\newlineThe given equation is: xy3+yx2=0-xy^{3} + y - x^{2} = 0.\newlineDifferentiate each term with respect to xx.
  2. Product rule: Differentiate xy3-xy^{3} with respect to xx using the product rule ddx[uv]=u(v)+v(u)\frac{d}{dx}[uv] = u'(v) + v'(u), where u=xu = x and v=y3v = y^{3}. The derivative of xx with respect to xx is 11, and the derivative of y3y^{3} with respect to xx is xx00 by the chain rule. So, the derivative of xy3-xy^{3} is xx22.
  3. Differentiate yy: Differentiate yy with respect to xx.\newlineSince yy is a function of xx, its derivative is dydx\frac{dy}{dx}.\newlineSo, the derivative of yy is dydx\frac{dy}{dx}.
  4. Differentiate x2-x^2: Differentiate x2-x^{2} with respect to xx. The derivative of x2-x^{2} with respect to xx is 2x-2x.
  5. Combine derivatives: Combine the derivatives of each term to get the derivative of the entire left side of the equation.\newlineThe combined derivative is: y33xy2(dydx)+(dydx)2x=0-y^{3} - 3xy^{2}\left(\frac{dy}{dx}\right) + \left(\frac{dy}{dx}\right) - 2x = 0.
  6. Solve for (\frac{dy}{dx}): Now, we need to solve for \((\frac{dy}{dx}). Group the terms containing \((\frac{dy}{dx}) on one side and the rest on the other side. \(\(3xy^{22}(\frac{dy}{dx}) - (\frac{dy}{dx}) = y^{33} + 22x.
  7. Factor out dydx\frac{dy}{dx}: Factor out dydx\frac{dy}{dx} from the left side of the equation.\newline\left(\frac{dy}{dx}\right)(\(3xy^{22} - 11) = y^{33} + 22x.
  8. Isolate (dydx):</b>Dividebothsidesoftheequationby$(3xy21)(\frac{dy}{dx}):</b> Divide both sides of the equation by \$(3xy^{2} - 1) to isolate (dydx)(\frac{dy}{dx}).\newline(dydx)=y3+2x3xy21(\frac{dy}{dx}) = \frac{y^{3} + 2x}{3xy^{2} - 1}.
