Excel for Engineers - Introduction to the FORECAST Function

In this video, I introduce you to the FORECAST function in Excel. The FORECAST function can be used to perform a linear interpolation automatically - without any complicated equations. I'll also walk you through an example where we will use the FORECAST function to interpolate in a table of fluid properties.
If you're unfamiliar with the concept of linear interpolation, you may want to check out a video I created on the topic at: bit.ly/dcytinterpolation
Note: In Excel 2016 the FORECAST function was replaced by the FORECAST.LINEAR function. Other than that, same use case.
