Frequently Asked Question

How to do Linear Approximation

Doing the linear approximation is easy using the linear approximation error calculator as it uses some simple steps,

Firstly, choose a point near the function you want to approximate.
Now determine the slope of the function on that point.
Use the point-slope form and write the equation at the chosen point.
Now approximate the function by using the equation.

What is Linear Approximation

Linear approximation is a method to approximate the value of a function near a specific point. In linear approximation, an equation is used to find the tangent line at that point. Due to this, linear approximation is also called as the tangent line approximation or linearization. This equation is also used by linearize calculator.

How to Find Linear Approximation

Finding the linear approximation is easy because of linearize equation calculator which gives steps to solve it. These steps are as follows,

Choose a point near which you want to approximate the given function.
Calculate the slope of the given function by determining its derivative and write the equation of tangent line using the point-slope form
Now apply the equation of linear approximation which is
$$ L(x) \;=\; f(a) + f’(a)(x - a) $$

How to Know if Linear Approximation is Over or Under

To know whether the linear approximation is over or under, linearisation calculator compares the value of the function at a point of interest to the point of linear approximation, here are some steps:

Calculate the function f(x) and the point of the interest x = a.
Now calculate the linear approximation on the same point.
If the function’s value on the point of interest is greater than the linear approximation on the point then the approximation is under the function but if the function’s value is lesser than the linear approximation then the approximation overestimates the function.

Is Linear Approximation the Same as Tangent Line

Yes, linear approximation is the same as the tangent line of the function at a specific point. This is because the linear approximation is about calculating the equation of a straight line. This line closely approximates the behavior of the function. The approximation here is achieved using the tangent line of the function.

Tangent line is a straight line at a point that touches the curve of the point on the point. It is the same slope as the function at that point. In linearization of a function calculator, The tangent line equation is used to find the behavior of the function. Hence, the tangent line and linear approximation are closely related to each other.
