Q. Given the function y=2x333+2x3 y=\frac{2 x^{3}-3}{3+2 x^{3}} , find dydx \frac{d y}{d x} in simplified form.\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Identify Function: Identify the function that needs to be differentiated.\newlineWe are given the function y=2x333+2x3y=\frac{2x^{3}-3}{3+2x^{3}}. We need to find its derivative with respect to xx, which is denoted as dydx\frac{dy}{dx}.
  2. Apply Quotient Rule: Apply the quotient rule for differentiation.\newlineThe quotient rule states that if we have a function y=uvy = \frac{u}{v}, where both uu and vv are functions of xx, then the derivative of yy with respect to xx is given by dydx=vdudxudvdxv2\frac{dy}{dx} = \frac{v\frac{du}{dx} - u\frac{dv}{dx}}{v^2}. Here, u=2x33u = 2x^3 - 3 and v=3+2x3v = 3 + 2x^3.
  3. Differentiate uu: Differentiate uu with respect to xx. The derivative of u=2x33u = 2x^3 - 3 with respect to xx is dudx=6x2\frac{du}{dx} = 6x^2.
  4. Differentiate vv: Differentiate vv with respect to xx. The derivative of v=3+2x3v = 3 + 2x^3 with respect to xx is dvdx=6x2\frac{dv}{dx} = 6x^2.
  5. Apply Quotient Rule: Apply the quotient rule using the derivatives from steps 33 and 44.\newlineSubstitute (du)/(dx)(du)/(dx) and (dv)/(dx)(dv)/(dx) into the quotient rule formula to get (dy)/(dx)=(3+2x3)(6x2)(2x33)(6x2)(3+2x3)2(dy)/(dx) = \frac{(3 + 2x^3)(6x^2) - (2x^3 - 3)(6x^2)}{(3 + 2x^3)^2}.
  6. Expand Numerator: Expand the numerator of the derivative.\newlineExpanding the numerator, we get (dy)/(dx)=(18x2+12x512x5+18x2)/((3+2x3)2)(dy)/(dx) = (18x^2 + 12x^5 - 12x^5 + 18x^2)/((3 + 2x^3)^2).
  7. Simplify Numerator: Simplify the numerator.\newlineNotice that the terms +12x5+12x^5 and 12x5-12x^5 cancel each other out. So, we have (dy)/(dx)=(18x2+18x2)/((3+2x3)2)(dy)/(dx) = (18x^2 + 18x^2)/((3 + 2x^3)^2).
  8. Combine Like Terms: Combine like terms in the numerator. Combining like terms, we get dydx=36x2(3+2x3)2\frac{dy}{dx} = \frac{36x^2}{(3 + 2x^3)^2}.
