1
Physics
velocity, acceleration, force
Velocity is the derivative of position; acceleration is the derivative of velocity. Newton built mechanics from calculus.
2
Economics
marginal cost, profit maximisation
Marginal cost = derivative of total cost. Profit is maximised where marginal revenue = marginal cost.
3
Engineering
structural stress analysis
Stress, strain, fluid flow, heat transfer — every engineering equation involves derivatives or integrals.
4
Medicine
drug concentration over time
5
AI
gradient descent in neural networks
Gradient descent uses derivatives to train every neural network. Without calculus, modern AI does not exist.
6
Astronomy
orbital mechanics
