Derivative Rules and Their Applications
Basic Derivative Rules
The derivative of a function measures the rate at which the function changes with respect to its variable. Several fundamental rules allow us to compute derivatives efficiently.
Power Rule: For , the derivative is .
Sum Rule: For , the derivative is .
Product Rule: For , the derivative is .
Quotient Rule: For , the derivative is .
Chain Rule: For , the derivative is .
