# Area Differential

Area differential, abbreviated as \(\Delta A\), is the difference between an expanded or reduced area of an object.

### Area Differential FORMULA

\(\large{ \Delta A = A_f - A_i }\)

Where:

\(\large{ \Delta A }\) = area differential

\(\large{ A_f }\) = final area

\(\large{ A_i }\) = initial area
