Applied mathematics

Build models with variables, assumptions, and units, test predictions, and revise limitations.

Meaning

Applied mathematics models key relationships in real problems using variables, equations, probability, and computation. Tools are selected to fit assumptions and data in contexts such as physics, engineering, biology, and economics.

Example

If a simplified model assumes no inflow and a loss of 10% of the water each hour, the amount is multiplied by each hour. Starting with 100 L predicts 81 L after two hours.A model's answer is a prediction under its assumptions. Use data to check whether drainage is proportional and whether it changes with the amount of water or the time interval.

Learning goal

Build models with variables, assumptions, and units, test predictions, and revise limitations.

Helpful background

Explore the functions, data, probability, differential equations, or optimization relevant to the phenomenon.

Units and prediction checks in dynamic models

These tasks do not assess measurement-error analysis or all models in physics, engineering, biology, and economics.
