Q. If xy+5y2x3=0 x y+5 y^{2}-x^{3}=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. Differentiation with Product Rule: We are given the equation xy+5y2x3=0xy + 5y^2 - x^3 = 0. To find dydx\frac{dy}{dx}, we will differentiate both sides of the equation with respect to xx, using implicit differentiation.
  2. Differentiation with Chain Rule: Differentiate xyxy with respect to xx. Using the product rule, the derivative of xyxy with respect to xx is y+xdydxy + x\frac{dy}{dx}.
  3. Differentiation of x3-x^3: Differentiate 5y25y^2 with respect to xx. Since yy is a function of xx, we use the chain rule. The derivative of 5y25y^2 with respect to xx is 10ydydx10y\frac{dy}{dx}.
  4. Combining Derivatives: Differentiate x3-x^3 with respect to xx. The derivative of x3-x^3 with respect to xx is 3x2-3x^2.
  5. Isolating (dydx):(\frac{dy}{dx}): Combine the derivatives from the previous steps to rewrite the differentiated equation: y+x(dydx)+10y(dydx)3x2=0y + x(\frac{dy}{dx}) + 10y(\frac{dy}{dx}) - 3x^2 = 0.
  6. Isolating (dy)/(dx)(dy)/(dx): Combine the derivatives from the previous steps to rewrite the differentiated equation: y+x(dy)/(dx)+10y(dy)/(dx)3x2=0y + x(dy)/(dx) + 10y(dy)/(dx) - 3x^2 = 0.Now, we need to solve for (dy)/(dx)(dy)/(dx). First, move all terms not containing (dy)/(dx)(dy)/(dx) to the other side of the equation: x(dy)/(dx)+10y(dy)/(dx)=3x2yx(dy)/(dx) + 10y(dy)/(dx) = 3x^2 - y.

First, move all terms not containing dydx\frac{dy}{dx} to the other side of the equation: xdydx+10ydydx=3x2yx\frac{dy}{dx} + 10y\frac{dy}{dx} = 3x^2 - y.Factor out dydx\frac{dy}{dx} from the left side of the equation: dydx(x+10y)=3x2y\frac{dy}{dx}(x + 10y) = 3x^2 - y.
  8. Isolating (dy)/(dx)(dy)/(dx): Combine the derivatives from the previous steps to rewrite the differentiated equation: y+x(dy)/(dx)+10y(dy)/(dx)3x2=0y + x(dy)/(dx) + 10y(dy)/(dx) - 3x^2 = 0.Now, we need to solve for (dy)/(dx)(dy)/(dx). First, move all terms not containing (dy)/(dx)(dy)/(dx) to the other side of the equation: x(dy)/(dx)+10y(dy)/(dx)=3x2yx(dy)/(dx) + 10y(dy)/(dx) = 3x^2 - y.Factor out (dy)/(dx)(dy)/(dx) from the left side of the equation: (dy)/(dx)(x+10y)=3x2y(dy)/(dx)(x + 10y) = 3x^2 - y.Divide both sides of the equation by (x+10y)(x + 10y) to isolate (dy)/(dx)(dy)/(dx): (dy)/(dx)=(3x2y)/(x+10y)(dy)/(dx) = (3x^2 - y) / (x + 10y).
