Introduction to Linear Approximation Calculator
Linearization of a function calculator is an online tool that linearizes a function at a particular point. It helps to approximate the value of a function using the approximation formula. It enables the students and mathematicians to understand how a function or curve behaves at a particular point. A linearization calculator uses a tangent line equation as a general function to approximate the given function. Comparing a function is a lengthy and tough process. Here we introduce an online tool that can help find the approximate value of a given function quickly.
How does the linear calculator work?
Local Linear Approximation Calculator uses a tangent line equation to find an approximation of a function at a given position. linearization of a function calculator finds the equation of the tangent at a given point to approximate a given function.
Linear Approximation is sometimes referred to as Linearization or Tangent Line Approximation. It is a calculus method that uses the tangent line to approximate another point on a curve.
Linear Approximation is a method that estimates the values of f (x) as long as it is near x = a. The Tangent line equation is shown below,
$$ ? \;=\;?(?) \;+ \;?′(?)(? \;− \;?) $$
Where f(a) is the function of a curve, f’(a) is the function's first derivative, or it is also known as the slope of the tangent line at a. It is the method of determining the line equation that is nearer estimation for a given function at x=a.
Example: Find the linearization of
$$ ?(?)\;=\;3x^3 \;at \;a\;=\;1 $$
First substitute the value of a in f(x) to find f(a).
$$ ?(?) \;=\; ?(1) \;=\; 3(1)^2 \;=\; 3 $$
So we have the point (1,3).
Now find the value of f’(x)
$$ ?′(?) \;=\; 6? $$
$$ ?′(?) \;=\; ?′(1) \;=\; 6(1) \;=\; 6 $$
Equation of tangent line is,
$$ ? \;=\; ?(?) \;+\; ?′(?)(? \;−\; ?) $$
Substituting the values of f(a), f’(a) and a
$$ ? = 3 + 6(? − 1) $$
$$ ? = 3 + 6? − 6 $$
$$ ? = 6? − 3 $$
This is the required solution for the given function. Here you have seen that approximating a curve may be a lengthy process.
How to find the linearization
There are straightforward, easy steps for computing a linear approximation of a function.
- You need to write the function in the Enter “Function” box in step one.
