Vedclass · Answer

(C) Given $y = b \cos \log \left( \frac{x}{n} \right)^n$. Using the chain rule,we differentiate with respect to $x$: $\frac{dy}{dx} = -b \sin \left( \log \left( \frac{x}{n} \right)^n \right) \cdot \frac{d}{dx} \left( \log \left( \frac{x}{n} \right)^n \right)$. Using the property of logarithms,$\log \left( \frac{x}{n} \right)^n = n \log \left( \frac{x}{n} \right)$. So,$\frac{d}{dx} \left( n \log \left( \frac{x}{n} \right) \right) = n \cdot \frac{1}{x/n} \cdot \frac{1}{n} = \frac{n}{x}$. Therefore,$\frac{dy}{dx} = -b \sin \left( \log \left( \frac{x}{n} \right)^n \right) \cdot \frac{n}{x} = -\frac{nb}{x} \sin \log \left( \frac{x}{n} \right)^n$.

If $y = b \cos \log \left( \frac{x}{n} \right)^n$,then $\frac{dy}{dx} = $
