A.7.5 sqrt 1+4e^-2 -e^-4 <<<<not sure though

B.7.5 sqrt 4-2e^-2 + e^-4

C.7.5 sqrt 4+4e^-2 - e^-4

D.7.5 sqrt 5-2e^-2 + e^-4

- Calculus-typo? -
**MathMate**, Sunday, March 13, 2011 at 10:02pmI integrated the expression

15(1-e^(-t/2))

and got: 15(1-e^(-t/2)).

When evaluated from 0 to 4 I got:

30*%e^(-2)+30

Divide by (4-0) gives 7.5(e^-2+1)=8.5

Could there be a typo somewhere?
