## Introduction to Linear Approximation Calculator

Linear approximation calculator uses linear function to calculate a general function. You can calculate the linear approximations of parametric, polar, or explicit curves at a given point. Using manual calculations can take a lot of time so linearization calculator help us evaluate the derivative to find the slope of entered points.

## Formula used by Linearization Calculator

The linearization calculator uses linear approximation formula to find the function. This will enable you to eveluate the derivative of a function to find the slope of a curve. Since linear approximation calculator uses the same linear approximation formula, you just need to enter your value and the tool will automatically provide accurate results.

The linear approximation formula used by this tangent line approximation calculator is:

$$ y \;=\; f(a) \;+\; f'(a)(x-a) $$

You can use this linear approximation formula to calculate manually or use our tool to calculate digitally as well.
