It is a valuable tool for students and professionals or teachers who want to learn the concept of finding the estimated value from the given function using the tangent line at a specific point in a few seconds

## What Is Linear Approximation?

Linear approximation is a process that is used to **approximate the value** of a given function at a point using a function. It is based on a continuous function that is differentiable at a point as it gives the approximate value on a curve.

Linear approximation is used in various fields like engineering to simplify complex systems and solve differential equations, in physics, it is used to find the systems near equilibrium points, and in economics, it finds the economic models and financial forecasts projects.

## How To Calculate Linear Approximation?

Linear approximation **calculates the estimated value** of a function near a given point using the tangent line at that point. Here is a step-by-step guide to calculating a linear approximation:

**Step 1**:

Identify the Function f(x) and you want to approximate it near the point x=a.

**Step 2**:

Find the Function f(x) at x=a as f(a)

**Step 3**:

Compute the derivative of the given function with respect to x. After derivation put the point in the derivation function as f`(x)=f`(a)

**Step 4**:

The linear approximation of f(x) at x=a can be written as:

$$ L(x) \;=\; f(a) + f′(a)(x − a) $$

**Step 5**:

Put the above values in this formula to get the linear approximate value and value to sketch a graph

## Solved Example Of Linear Approximation:

The linearization calculator is here to help you solve the linear approximation problems. So, an **example** is given below,

**Example**:

Approximating √x near x = 4.

**Solution**:

Determine the approximation function,

$$ f(x) \;=\; \sqrt{x}\; near\; x \;=\; 4 $$

Find the derivative of a given function with respect to x,

$$ f’(x) \;=\; \frac{1}{2\sqrt{x}} $$

Evaluate the point x = 4 in derivative function f`(4),

$$ f’(4) \;=\; \frac{1}{2\sqrt{4}} \;=\; \frac{1}{2.2} \;=\; \frac{1}{4} $$

Evaluate the point x=4 in derivative function f(4),

$$ f(4) \;=\; \sqrt{4} \;=\; 2 $$

The formula of linear approximation is,

$$ f(x) \approx f(a) + f’(a) . (x - a) $$

Put the value of the linear approximation formula,

$$ f(x) \approx 2 + \frac{1}{4}(x - 4) $$

$$ =\; 2 + \frac{1}{4}(0.1) \;=\; 2 + 0.025 \;=\; 2.025 $$
