However, what if the field in question had to be measured very accurately? Then, one might need some vector calculus and find the line integral.
Just easy math in every farmers' daily work 
You know, I never thought about it before, but I should never be a farmer because I probably would try to be too perfect with things like that.... |
Q: Why does a farmer need good math skills?
A: Because when they protect their crops -- too little pesticide means they lose more of the crop, too much pesticide means they wasted money on excess spraying, and not following the mathematical instructions on the pesticide label means they can go to jail. Use of pesticides in any manner for which they are not specifically labelled is a crime -- the warning is printed on every label.
