# Area Differential

Written by Jerry Ratzlaff on . Posted in Geometry

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
