Numerical Methods

Numerical Methods involves algorithms and techniques for solving mathematical problems numerically rather than analytically.

Advanced Topics

Interpolation and Curve Fitting

Filling In the Gaps

Sometimes we only have a few data points, but we want to estimate values in between or find a smooth curve that fits our data.

Interpolation

  • Linear Interpolation: Connects data points with straight lines.
  • Polynomial Interpolation: Uses curves to fit more complex patterns.

Curve Fitting

  • Finds a function (like a line or parabola) that best fits the data, often using the least squares method.

Why Is This Useful?

  • Allows predictions where no data exists.
  • Makes sense of noisy or incomplete data.

Everyday Impact

From predicting tomorrow’s temperature to creating smooth graphics in video games, interpolation and curve fitting are everywhere.

Examples

  • Predicting the next value in a weather data set.

  • Fitting a smooth line to population growth data.

In a Nutshell

Interpolation and curve fitting help us estimate missing values and find trends in data.
