What are some common mistakes in derivative calculations?

Some common mistakes include forgetting the chain rule, misapplying product and quotient rules, and arithmetic errors.

Can you explain the chain rule with an example?

Sure! The chain rule states that if you have a composite function, you differentiate the outer function and multiply it by the derivative of the inner function. For example, if you have f(g(x)), the derivative is f'(g(x)) * g'(x).

What about the product and quotient rules?

The product rule states that if you have two functions multiplied together, the derivative is u'v + uv'. The quotient rule is similar: for u/v, the derivative is (u'v - uv')/v².

How can I avoid these mistakes in my calculations?

Practice is key! Always double-check your work, and consider writing out each step clearly to avoid skipping any rules.
