Q. If 4y2+y3+2+5x3=0 -4 y^{2}+y^{3}+2+5 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. Given Equation: We are given the equation 4y2+y3+2+5x3=0-4y^{2} + y^{3} + 2 + 5x^{3} = 0 and we need to find the derivative of yy with respect to xx, denoted as dydx\frac{dy}{dx}. To do this, we will implicitly differentiate both sides of the equation with respect to xx.
  2. Implicit Differentiation: Differentiate each term of the equation with respect to xx. For the terms involving yy, we will use the chain rule, treating yy as a function of xx (y=y(x)y = y(x)). This means that when we differentiate yy terms, we multiply by dydx\frac{dy}{dx} after taking the derivative with respect to yy.
  3. Differentiate Terms: Differentiating 4y2-4y^{2} with respect to xx gives us 8ydydx-8y\frac{dy}{dx}, because the derivative of y2y^{2} with respect to yy is 2y2y, and then we multiply by dydx\frac{dy}{dx} due to the chain rule.
  4. Derivative of Constant: Differentiating y3y^{3} with respect to xx gives us 3y2dydx3y^{2}\frac{dy}{dx}, because the derivative of y3y^{3} with respect to yy is 3y23y^{2}, and then we multiply by dydx\frac{dy}{dx} due to the chain rule.
  5. Combine Differentiated Terms: The derivative of the constant term 22 with respect to xx is 00, because the derivative of any constant is 00.
  6. Factor Out (dy)/(dx)(dy)/(dx): Differentiating 5x35x^{3} with respect to xx gives us 15x215x^{2}, because the derivative of x3x^{3} with respect to xx is 3x23x^{2}.
  7. Isolate (dy)/(dx)(dy)/(dx): Putting it all together, the differentiated equation is:\newline\(-8y\frac{dy}{dx} + 33y^{22}\frac{dy}{dx} + 00 + 1515x^{22} = 00
  8. Final Solution: Now we need to solve for dydx\frac{dy}{dx}. We can factor dydx\frac{dy}{dx} out of the terms that contain it:\newlinedydx(8y+3y2)+15x2=0\frac{dy}{dx}(-8y + 3y^{2}) + 15x^{2} = 0
  9. Final Solution: Now we need to solve for dydx\frac{dy}{dx}. We can factor dydx\frac{dy}{dx} out of the terms that contain it:\newlinedydx(8y+3y2)+15x2=0\frac{dy}{dx}(-8y + 3y^{2}) + 15x^{2} = 0To isolate dydx\frac{dy}{dx}, we move the term not containing dydx\frac{dy}{dx} to the other side of the equation:\newlinedydx(8y+3y2)=15x2\frac{dy}{dx}(-8y + 3y^{2}) = -15x^{2}
  10. Final Solution: Now we need to solve for dydx\frac{dy}{dx}. We can factor dydx\frac{dy}{dx} out of the terms that contain it: dydx(8y+3y2)+15x2=0\frac{dy}{dx}(-8y + 3y^{2}) + 15x^{2} = 0 To isolate dydx\frac{dy}{dx}, we move the term not containing dydx\frac{dy}{dx} to the other side of the equation: dydx(8y+3y2)=15x2\frac{dy}{dx}(-8y + 3y^{2}) = -15x^{2} Finally, we divide both sides of the equation by (8y+3y2)(-8y + 3y^{2}) to solve for dydx\frac{dy}{dx}: dydx=15x28y+3y2\frac{dy}{dx} = \frac{-15x^{2}}{-8y + 3y^{2}}
