Q. If 5y+y3y2x3=0 5 y+y^{3}-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. Given Equation: We are given the equation 5y+y3y2x3=05y + y^3 - y^2 - x^3 = 0 and we need to find the derivative of yy with respect to xx, which is dydx\frac{dy}{dx}. To do this, we will use implicit differentiation, which involves taking the derivative of both sides of the equation with respect to xx, while treating yy as a function of xx.
  2. Implicit Differentiation: First, we differentiate each term of the equation with respect to xx. For the terms involving yy, we will apply the chain rule, which states that the derivative of a function of a function is the derivative of the outer function times the derivative of the inner function. In this case, the "inner function" is yy, which is a function of xx, so we multiply by dydx\frac{dy}{dx} after differentiating with respect to yy.
  3. Differentiating 5y5y: Differentiating 5y5y with respect to xx gives us 5dydx5\frac{dy}{dx}, since the derivative of yy with respect to xx is dydx\frac{dy}{dx}.
  4. Differentiating y3y^3: Differentiating y3y^3 with respect to xx gives us 3y2dydx3y^2\frac{dy}{dx}, by applying the chain rule (the derivative of y3y^3 with respect to yy is 3y23y^2, and then we multiply by dydx\frac{dy}{dx}).
  5. Differentiating y2-y^2: Differentiating y2-y^2 with respect to xx gives us 2ydydx-2y\frac{dy}{dx}, by applying the chain rule (the derivative of y2y^2 with respect to yy is 2y2y, and then we multiply by dydx\frac{dy}{dx}.
  6. Differentiating x3-x^3: Differentiating x3-x^3 with respect to xx gives us 3x2-3x^2, since xx is the variable we are differentiating with respect to.
  7. Combining Differentiated Terms: Now we combine all the differentiated terms to rewrite the equation: 5(dydx)+3y2(dydx)2y(dydx)3x2=05\left(\frac{dy}{dx}\right) + 3y^2\left(\frac{dy}{dx}\right) - 2y\left(\frac{dy}{dx}\right) - 3x^2 = 0.
  8. Factoring out dydx\frac{dy}{dx}: We can factor out dydx\frac{dy}{dx} from the terms that contain it: (dydx)(5+3y22y)3x2=0\left(\frac{dy}{dx}\right)(5 + 3y^2 - 2y) - 3x^2 = 0.
  9. Isolating dydx\frac{dy}{dx}: Now we isolate dydx\frac{dy}{dx} by adding 3x23x^2 to both sides and then dividing by (5+3y22y)(5 + 3y^2 - 2y): dydx=3x25+3y22y\frac{dy}{dx} = \frac{3x^2}{5 + 3y^2 - 2y}.
