What is the first derivative?Show answer
The first derivative measures the instantaneous rate of change. Its sign reveals function behaviour.
What is the second derivative?Show answer
The second derivative measures the rate of change of , equivalent to the concavity of .
What is the optimisation method?Show answer
Every optimisation problem follows the same five steps.
What is related rates of change?Show answer
When two or more related quantities change with time, the chain rule links their rates.
