To find the derivative of a function, you would apply the rules of differentiation, such as:

1. Power Rule:
   For $f(x) = x^n$, the derivative is $f'(x) = n \cdot x^{n-1}$.

2. Product Rule:
   For $f(x) = u(x) \cdot v(x)$, the derivative is
   $f'(x) = u'(x) \cdot v(x) + u(x) \cdot v'(x)$.

3. Quotient Rule:
   For $f(x) = \frac{u(x)}{v(x)}$, the derivative is
   $f'(x) = \frac{u'(x) \cdot v(x) - u(x) \cdot v'(x)}{v(x)^2}$.

4. Chain Rule:
   For a composite function $f(g(x))$, the derivative is
   $f'(x) = f'(g(x)) \cdot g'(x)$.

These rules can be applied individually or in combination depending on the form of the function you wish to differentiate.

Do you have a specific function you'd like to find the derivative of?

Here are some relevant questions to deepen your understanding:

1. What is the derivative of $f(x) = x^3$?
2. How do you differentiate $f(x) = e^{2x}$?
3. What is the product rule used for?
4. How would you find the derivative of $\sin(x) \cdot \cos(x)$?
5. How does the chain rule apply to $f(x) = \sin(3x)$?

Tip: When differentiating complex functions, break them down into smaller parts and apply the rules systematically.
