Annual sales (in millions of units) of pocket computers are expected to grow in accordance with the following function where t is measured in years, with t = 0 corresponding to 1997.
f(t) = 0.18t^2 + 0.16t + 2.64
How many pocket computers will be sold over the 2 year period between the beginning of 1997 and the end of 1998?
NOTE: I got 1.04 but it says it is wrong.

Hmmm. we have
∫[0,2] 0.18t^2 + 0.16t + 2.64
= 0.06t^3 + 0.08t^2 + 2.64t [0,2]
= .48 + .32 + 5.28
= 6.08
What did you do to arrive at your answer?
1.04 is obviously way off, since f(0) = 2.64 just to start with. 
I did my math wrong, I don't know what I was thinking. Thanks for your help.
