Q. If x2+2y3+3y=y2+5 -x^{2}+2 y^{3}+3 y=y^{2}+5 then find dydx \frac{d y}{d x} in terms of x x and y y .\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Rewrite Equation: First, we need to rewrite the given equation to make it easier to differentiate with respect to xx. The equation is x2+2y3+3y=y2+5-x^{2} + 2y^{3} + 3y = y^{2} + 5.
  2. Differentiate with Respect to xx: Now, we will differentiate both sides of the equation with respect to xx. Remember that when differentiating terms with yy, we treat yy as a function of xx and use the chain rule to include dydx\frac{dy}{dx}.
  3. Left Side Differentiation: Differentiate the left side of the equation with respect to xx: ddx(x2+2y3+3y)\frac{d}{dx}(-x^{2} + 2y^{3} + 3y). This gives us 2x+2×3y2×dydx+3×dydx-2x + 2 \times 3y^{2} \times \frac{dy}{dx} + 3 \times \frac{dy}{dx}.
  4. Right Side Differentiation: Differentiate the right side of the equation with respect to xx: ddx(y2+5)\frac{d}{dx}(y^{2} + 5). This gives us 2ydydx+02y \cdot \frac{dy}{dx} + 0, since the derivative of a constant is 00.
  5. Solve for (\frac{dy}{dx}): Now we have the following equation from the derivatives: \(\(-2x + 66y^{22} \cdot (\frac{dy}{dx}) + 33 \cdot (\frac{dy}{dx}) = 22y \cdot (\frac{dy}{dx}).
  6. Collect Terms: We need to solve for dydx\frac{dy}{dx}. To do this, we'll collect all the terms with dydx\frac{dy}{dx} on one side of the equation and the rest on the other side. This gives us 6y2dydx+3dydx2ydydx=2x6y^{2} \cdot \frac{dy}{dx} + 3 \cdot \frac{dy}{dx} - 2y \cdot \frac{dy}{dx} = 2x.
  7. Factor Out (dydx):</b>Factorout$(dydx)(\frac{dy}{dx}):</b> Factor out \$(\frac{dy}{dx}) from the left side of the equation: (dydx)(6y2+32y)=2x(\frac{dy}{dx}) \cdot (6y^{2} + 3 - 2y) = 2x.
  8. Isolate (dydx):</b>Now,isolate$(dydx)(\frac{dy}{dx}):</b> Now, isolate \$(\frac{dy}{dx}) by dividing both sides of the equation by (6y2+32y):$dydx=2x6y2+32y(6y^{2} + 3 - 2y): \$\frac{dy}{dx} = \frac{2x}{6y^{2} + 3 - 2y}.
