6.5 Definite Integrals Annual sales in millions of units of hand-held computers were expected to grow in accordance with f(t) = .18 t 2 + .16 t + 2.64, 0< t< 6. where t is in years and t = 0 corresponds to 1997. How many hand-held computers were sold over the 1- year period between the beginning of 1997 and the end of 1997? 0 1 f(t) = 2.78 million (select) Evaluate the given definite integral 11 14 -5(x - 10) (3/2) dx -62 Evaluate the definite integral -1 0 (x 2 - 1 )/ (x 3 – 3x +1 ) dx
