The graph below indicates the number of new cases of Chalk Dust Disease (CDD) diagnosed each month in the Mathland. Let T(t) represent the total number of new cases per month, F(t) the number of new cases per year among algebraists, G(t) the number of new cases per year among geometers, and t the number of years since January 1, 1990.
Estimate (T - G)(1) and interpret its meaning.
