An online linear interpolation calculator helps to find the interpolated values for the data points on a line or a curve. The calculator plots the interpolated point on a line and shows a step-by-step solution by using linear interpolation formula.
Just read the context to get the basic insight about how to do interpolation, its formula, and some standard terms that help to understand interpolating.
Linear interpolation is a method of creating new data points in an already known discrete set of data points. In this mathematical procedure, some original data points can be interpolated to produce a simple and new function that will be close to the original data. This integration of new value is known as interpolating. In other words, we can also say that a Linear interpolant is a straight line that exists between the two recognized co-ordinate points (x0, y0) and (x1, y1). You can readily find the interpolant value between the two coordinates on a straight line by using a linear interpolation calculator.
Formula for Linear interpolation is
$$y = y1 + ((x – x1) / (x2 – x1)) * (y2 – y1)$$
In this interpolation equation:
Moreover, an Online Slope Calculator helps to find the slope or gradient points A (x1,y1) and B (y1,y2) in the Cartesian coordinate plane.
If the Given data points are (2, 4) and (6, 8), how will you calculate the value of y when x = 2.
In the first step, we will Extract the coordinates of the given data points.
In the second step, we will take the following equations to have the values of m and then y
Meanwhile, x is within the interval \([x1, x2]\), so we have done a linear interpolation calculation to find the value of y.
However, An Online Centroid Calculator helps you to find the centroid of a triangle (ABC), N-Points, and N-sided polygon for the given coordinates.
Find the value of \(y^2\) on a given line while the given data is
“$$x1 = 4, y1 = 6, x2 = 8, x3 = 12, y3 = 14$$”.
As We have linear interpolation equation:
$$y_2= (x_2 – x_1) x (y_3- y_1) / (x_3 – x_1) + y_1$$
A step by step solution to find y2 will be as by putting the in above equation as follows:
$$y_2= (x_3−x_2) x (y_3−y_1) / (x_3−x_2) +y_3$$
$$y_2= (12−8) x (14−6) / (12−8) +14$$
$$y_2= (4) x (8) / (4) +14$$
$$y_2= (32) / (4) +14$$
Here is the working procedure of the online calculator to figure out the linear interpolated values.
The online interpolation calculator will provide you the following results:
Usually, we use the Polynomials interpolating method. The reasons to use polynomials are:
This is known as polynomial interpolation.
As we already know that with Interpolation we can find out unknown points therefore It can be used whenever we need to predict unknown values for any geographic point data. It is helpful for the prediction of rainfall, resulted in chemical concentrations, assess the noise levels, and so on.
Inverse Distance Weighted (IDW) interpolation is considered as one of the best methods to achieve better results than any other interpolation method.
kriging interpolation technique is generally linked with exact interpolation. All the Kriging predictions can change progressively in space. They will case to change after getting to a location where data has been composed. At this point, there is a “jump” in the prediction to the most precise value that was first measured. However, an interpolator can be used to make quick and accurate predictions.
Thanks to the linear interpolation calculator for finding the unknown data point for given coordinates and plot the point on graphs. Also, this tool shows the formula which is used to fulfill the requirements with complete calculations step by step to facilitate the end-users with-in no time. It provides its support for learning and educational purposes without any cost. Hence let’s try to find the answer by putting the known data point in this interpolator!
