Q. Find the derivative of the following function.\newliney=ex3 y=e^{-x^{3}} \newlineAnswer: y= y^{\prime}=
  1. Identify Function Components: Identify the function and its components for differentiation.\newlineThe function y=ex3y = e^{-x^{3}} can be seen as an outer function eue^{u} where u=x3u = -x^{3}.
  2. Derivative of Outer Function: Determine the derivative of the outer function with respect to uu, where u=x3u = -x^{3}.\newlineThe derivative of eue^{u} with respect to uu is eue^{u}.\newlineSo, (d/du)(eu)=eu(d/du)(e^{u}) = e^{u}.
  3. Derivative of Inner Function: Find the derivative of the inner function uu with respect to xx, where u=x3u = -x^{3}. The derivative of x3-x^{3} with respect to xx is 3x2-3x^{2}. So, (ddx)(x3)=3x2(\frac{d}{dx})(-x^{3}) = -3x^{2}.
  4. Apply Chain Rule: Apply the chain rule to differentiate the composite function y=ex3y = e^{-x^{3}}.\newlineThe chain rule states that dydx=dydududx\frac{dy}{dx} = \frac{dy}{du} \cdot \frac{du}{dx}.\newlineWe have dydu=eu\frac{dy}{du} = e^{u} and dudx=3x2\frac{du}{dx} = -3x^{2}.\newlineTherefore, dydx=eu(3x2)\frac{dy}{dx} = e^{u} \cdot (-3x^{2}).
  5. Substitute and Simplify: Substitute uu back into the derivative to get the final answer.\newlineSince u=x3u = -x^{3}, we replace uu with x3-x^{3} in the derivative.\newlineSo, dydx=ex3(3x2)\frac{dy}{dx} = e^{-x^{3}} \cdot (-3x^{2}).
  6. Substitute and Simplify: Substitute uu back into the derivative to get the final answer.\newlineSince u=x3u = -x^{3}, we replace uu with x3-x^{3} in the derivative.\newlineSo, dydx=ex3(3x2)\frac{dy}{dx} = e^{-x^{3}} \cdot (-3x^{2}). Simplify the expression to get the final derivative.\newliney=3x2ex3y' = -3x^{2} \cdot e^{-x^{3}}.\newlineThis is the derivative of the function y=ex3y = e^{-x^{3}}.
