Key Concepts

Differential Approximation

This concept involves using the derivative of a function at a specific point to estimate the change in the function’s value for a small change in the input. It is based on the idea that for small changes, the function behaves approximately linearly, and the derivative provides the rate at which the function is increasing or decreasing.

Linearization

Linearization is a technique that uses the tangent line at a particular point to approximate the function near that point. The approximation f(a + ?x) ? f(a) + f?'(a)?x is derived from the first order Taylor expansion and is particularly useful for small values of ?x.

Error Estimation

This involves comparing the approximated value obtained through methods such as differential approximation or linearization to the actual value of the function. The error is the absolute difference between the true value and the estimated value, indicating how close the approximation is.

Percentage Error Calculation

Percentage error is a way to quantify the error relative to the true value by expressing it as a percentage. It is calculated by dividing the absolute error by the actual value and multiplying by 100, providing a normalized measure of how significant the error is in context.
