1. The problem is to find the derivative of a function using $\frac{dy}{dx}$ notation. 2. The derivative $\frac{dy}{dx}$ represents the rate of change of $y$ with respect to $x$. 3. To find $\frac{dy}{dx}$, apply differentiation rules such as the power rule, product rule, quotient rule, or chain rule depending on the function. 4. For example, if $y = x^n$, then $\frac{dy}{dx} = nx^{n-1}$ (power rule). 5. If you provide a specific function, I can show step-by-step how to compute $\frac{dy}{dx}$ for that function. 6. Please share the function you want to differentiate using $\frac{dy}{dx}$.
