Calculate the unknown value using the interpolation formula from the given set of data. Calculate the value of Y when X value is Harry shares details of Sales and profits. You are required to calculate profits based on the given data:. Based on the above data, we can estimate the profits of Mr.

Harry using the interpolation formula as follows:. Doing this graphical interpolation, you may find that about 95 students failed the math placement test in the year Know the formula for the linear interpolation process. Write down the numbers that you are going to put into the equation.

Since your unknown x value is the year , you will use the values in the table for and Put the values of the data into the linear interpolation formula. You should receive an answer of 95 students. Therefore, in the year , 95 students failed the math placement exam. Mara Pesacreta has been writing for over seven years. She has been published on various websites and currently attends the Polytechnic Institute of New York University.

When you are doing a linear interpolation, you are approximating the function between points as a line. From there, you can find the estimated value at any point between them. Therefore, you cannot ask the interpolation of a single number - rather, you need multiple numbers to determine your line, and from there you can ask what value you would expect at a point.

Linear interpolation has been used since antiquity for filling the gaps in tables. Suppose that one has a table listing the population of some country in , , and , and that one wanted to estimate the population in Linear interpolation is an easy way to do this.

The technique of using linear interpolation for tabulation was believed to be used by Babylonian astronomers and mathematicians in Seleucid Mesopotamia last three centuries BC , and by the Greek astronomer and mathematician, Hipparchus 2nd century BC. A description of linear interpolation can be found in the Almagest 2nd century AD by Ptolemy.

The basic operation of linear interpolation between two values is commonly used in computer graphics. The term can be used as a verb or noun for the operation.

Lerp operations are built into the hardware of all modern computer graphics processors. They are often used as building blocks for more complex operations: for example, bilinear interpolation can be accomplished in three lerps.

Let us say that we have two known points x 1 , y 1 x1,y1 and x 2 , y 2 x2,y2. Now we want to estimate what y y value we would get for some x x value that is between x 1 x1 and x 2 x2.
