Key Concepts

Linear Approximation

Linear approximation involves estimating the change in a function by using the tangent line at a specific point. When a small change occurs in the input, the function's new value can be approximated by the value of its linearization, which is derived from the function's derivative, assuming that the behavior of the function near that point is nearly linear.

Differentials

Differentials refer to the small changes in functions and their independent variables. The differential of a function, often denoted as df, provides an approximation of the actual change in the function for a small increment in the variable, calculated as the product of the derivative at that point and the small change in the variable.

Error Analysis

Error analysis in the context of linear approximation involves comparing the estimated change provided by the differential (or linear approximation) with the actual change in the function. This comparison helps in determining the accuracy of the approximation, particularly when the change in the input is not infinitesimally small.

Percentage Error

Percentage error quantifies the accuracy of an approximation by expressing the error as a percentage of the exact value. It is computed by dividing the absolute error by the exact value of the change and then multiplying by 100. This measure is useful for assessing the relative impact of the error in practical applications.
