Identifying which differentiation rule to use can be a bit tricky, but here are some tips from my experience:

1. Look at the Type of Function:

   • Power Rule: Use this when you see (x) raised to some power.
   • Product Rule: Apply this when you have two functions multiplied together, like (f(x) \cdot g(x)).
   • Quotient Rule: Use this when it’s a division, like (\frac{f(x)}{g(x)}).
   • Chain Rule: This is for composite functions, like (f(g(x))).

2. Break It Down:
   Always simplify complicated expressions first. This will help you see the parts more clearly.

3. Practice:
   The more problems you work on, the easier it will get to spot patterns!
