Q. If y2y35x3=y -y^{2}-y^{3}-5 x^{3}=y 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 y2-y^{2}: We are given the equation y2y35x3=y-y^{2} - y^{3} - 5x^{3} = y. To find dydx\frac{dy}{dx}, we need to differentiate both sides of the equation with respect to xx, treating yy as a function of xx (implicit differentiation).
  2. Differentiate y3-y^{3}: Differentiate the term y2-y^{2} with respect to xx. Since yy is a function of xx, we use the chain rule: the derivative of y2y^{2} with respect to yy is 2y2y, and then we multiply by dydx\frac{dy}{dx} (the derivative of yy with respect to xx).\newlineThe differentiation gives us y2-y^{2}11.
  3. Differentiate 5x3-5x^{3}: Differentiate the term y3-y^{3} with respect to xx. Using the chain rule again, the derivative of y3y^{3} with respect to yy is 3y23y^{2}, and then we multiply by (dy)/(dx)(dy)/(dx).\newlineThe differentiation gives us 3y2(dy)/(dx)-3y^{2}(dy)/(dx).
  4. Differentiate yy: Differentiate the term 5x3-5x^{3} with respect to xx. Since xx is the variable we are differentiating with respect to, we simply use the power rule: the derivative of x3x^{3} is 3x23x^{2}.\newlineThe differentiation gives us 15x2-15x^{2}.
  5. Combine and set equal: Differentiate the term yy with respect to xx. Since yy is a function of xx, the derivative is simply dydx\frac{dy}{dx}.\newlineThe differentiation gives us dydx\frac{dy}{dx}.
  6. Isolate (dy)/(dx)(dy)/(dx): Combine all the differentiated terms and set the equation equal to the derivative of the right side of the original equation, which is 00 since the derivative of a constant is 00. So, we have 2y(dy)/(dx)3y2(dy)/(dx)15x2=(dy)/(dx)-2y(dy)/(dx) - 3y^{2}(dy)/(dx) - 15x^{2} = (dy)/(dx).
  7. Factor out (dy)/(dx)(dy)/(dx): We need to solve for (dy)/(dx)(dy)/(dx). To do this, we isolate terms containing (dy)/(dx)(dy)/(dx) on one side of the equation.\newlineThis gives us (dy)/(dx)2y(dy)/(dx)3y2(dy)/(dx)=15x2(dy)/(dx) - 2y(dy)/(dx) - 3y^{2}(dy)/(dx) = 15x^{2}.
  8. Divide to solve for (dydx):</b>Factorout$(dydx)(\frac{dy}{dx}):</b> Factor out \$(\frac{dy}{dx}) from the left side of the equation.\newlineThis gives us (dydx)(12y3y2)=15x2.(\frac{dy}{dx})(1 - 2y - 3y^{2}) = 15x^{2}.
  9. Divide to solve for (dy)/(dx)(dy)/(dx): Factor out (dy)/(dx)(dy)/(dx) from the left side of the equation.\newlineThis gives us (dy)/(dx)(12y3y2)=15x2(dy)/(dx)(1 - 2y - 3y^{2}) = 15x^{2}.Divide both sides of the equation by (12y3y2)(1 - 2y - 3y^{2}) to solve for (dy)/(dx)(dy)/(dx).\newlineThis gives us (dy)/(dx)=15x212y3y2(dy)/(dx) = \frac{15x^{2}}{1 - 2y - 3y^{2}}.
