1. The problem is to find the derivative of a function. 2. Start by stating the function explicitly if known (e.g., $f(x)$). If the function is not provided, please specify it. 3. The derivative of a function $f(x)$ with respect to $x$ is denoted $f'(x)$ or $\frac{df}{dx}$. 4. Use differentiation rules such as the power rule: if $f(x) = x^n$, then $f'(x) = nx^{n-1}$. 5. Apply sum, product, or chain rules as necessary depending on the form of the function. 6. Simplify the resulting expression to get the final derivative. Please provide the function you want to differentiate to proceed with step-by-step differentiation.
