Vedclass · Answer

(A) Given $y = {\left( {1 + \frac{1}{x}} \right)^x}$.Taking the natural logarithm on both sides,we get $\log y = x \log \left( {1 + \frac{1}{x}} \right)$.Differentiating both sides with respect to $x$ using the product rule:$\frac{1}{y} \frac{dy}{dx} = \frac{d}{dx} \left[ x \log \left( {1 + \frac{1}{x}} \right) \right]$$\frac{1}{y} \frac{dy}{dx} = 1 \cdot \log \left( {1 + \frac{1}{x}} \right) + x \cdot \frac{1}{1 + \frac{1}{x}} \cdot \left( -\frac{1}{x^2} \right)$$\frac{1}{y} \frac{dy}{dx} = \log \left( {1 + \frac{1}{x}} \right) + x \cdot \frac{x}{x + 1} \cdot \left( -\frac{1}{x^2} \right)$$\frac{1}{y} \frac{dy}{dx} = \log \left( {1 + \frac{1}{x}} \right) - \frac{1}{x + 1}$Therefore,$\frac{dy}{dx} = y \left[ \log \left( {1 + \frac{1}{x}} \right) - \frac{1}{x + 1} \right] = {\left( {1 + \frac{1}{x}} \right)^x}\left[ \log \left( {1 + \frac{1}{x}} \right) - \frac{1}{x + 1} \right]$.

If $y = {\left( {1 + \frac{1}{x}} \right)^x}$,then $\frac{dy}{dx} = $
