noun a rough estimate or calculation
adjective approximately correct
In mathematics, approximation is used to represent a value that is close to the actual value but not exact. It is commonly used in numerical analysis, calculus, and statistics.
In engineering, approximation is used to simplify complex calculations or models to make them more manageable. It is often used in structural analysis, fluid dynamics, and control systems.
In computer science, approximation is used in algorithms and computational complexity theory to find efficient solutions to problems that may not have exact solutions. It is commonly used in optimization, machine learning, and data analysis.
In physics, approximation is used to make simplifications in complex physical systems to obtain approximate solutions. It is commonly used in quantum mechanics, thermodynamics, and astrophysics.
In the field of writing, approximation is used to convey information that may not be exact or precise, but is close enough for the intended purpose. Writers often use approximation when describing statistics, measurements, or historical events.
Psychologists use approximation when estimating the likelihood of certain behaviors or outcomes based on limited information. They may also use approximation when interpreting test results or making rough estimates of a client's mental health status.
Scientists frequently use approximation in their research to simplify complex calculations or models. Approximation allows scientists to make predictions and draw conclusions without needing exact data or measurements.
Engineers rely on approximation when designing structures, systems, or processes. They use approximations to estimate loads, stresses, and other factors that may affect the performance of their designs.
Accountants often use approximation when preparing financial statements or analyzing data. They may round numbers or use estimates to simplify calculations and present information in a clear and concise manner.
