Linear Interpolation

[SFares]

Hello,

Attached is a Mathcad Prime 9 sheet. I would like to perform linear interpolation as explained in the sheet. Thank you for your help.

Best regards,

Sam

This should do it. You may need to recalculate the sheet.

Note that you don't need the IF statements. The function linterp will do extrapolation from the last two points on either side of the range, so just extend the range with an extra point on either side...

Success!
