In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.
With the following data set, what is the best way to interpolate the data for each time.

$begingroup$You can use Newton's divided differences interpolation polynomial which is easy to use and if you add a new point to the set, you don't have to calculate everything again.
So you'll have a table with four columns, $x_i, y_i$ and divided differences where:
$$fleft[x_0,x_1,dots, x_nright]=dfrac{fleft[x_0,x_1,dots, x_{n-1}right]-fleft[x_1,dots, x_nright]}{x_0-x_n}$$
Then, for example, you have:
$x_0=10, y_0=15, x_1=28,y_1=17$:$$f[x_0,x_1]=dfrac{y_0-y_1}{x_0-x_1}=dfrac{15-17}{10-28}=0.11$$
$$f[x_1,x_2]=dfrac{17-14}{28-9}=0.15$$
$$f[x_0,x_1,x_2]=dfrac{0.11-0.15}{10-9}$$ Install uk tv now on kodi what is checker.
Thus, the interpolating polynomial is:
$$p(x)=f_0+(x-x_0)f[x+0,x_1]+dots+(x-x)dots(x-x_{n-1})f[x+0,dots,x_n]$$
And it's easy to take it from here.
