Formula for linear approximation
The linear approximation formula can be used to approximate a nonlinear function by a linear function. The formula is:
y = f(x) + f'(x) * (x – a)
Where y is the approximate value, f(x) is the original function, f'(x) is the derivative of f(x), and a is the point at which the approximation is being made.
Linear Approximation Definition
Linear approximation is a mathematical concept used to describe the relationship between two variables that are evenly distributed around a central value. The linear approximation is the arithmetic mean of the two outermost values in a distribution.
Example of linear approximation based on Formula
The linear approximation of a function f(x) at a point x0 is given by the formula:
f(x) ≈ f(x0) + f'(x0)(x – x0)
where f'(x0) is the derivative of f(x) at x0.
For example, if the function f(x) is given by f(x) = x2 and the point x0 is given by x0 = 1, then the linear approximation of f(x) at x0 is given by f(x) ≈ f(x0) + f'(x0)(x – x0) = f(1) + f'(1)(x – 1) = 1 + 2(x – 1) = 2x – 1.
