In this article it is possible to see both of those with the values we calculated fall concerning vales stated while in the table so we must perform a bilinear interpolation. To avoid wasting time we’ll just use a web based calculator to learn that, link listed here (look at the online video to learn the way to carry out a bilinear interpolation).
