an exam though about this as it is unclear)

10) we didn't discuss this although true
11)E (note that you don't have to do any calculation to get this (other than simple
divisionsi.e. knowing that the midpoint of 2 and 4 is 3). Also note that in
general on these type of problems, it is enough to figure out whether your next
guess is positive or negative rather than calculating the exact value. For example,
if at one step you have your lower guess is 2 and your upper guess is 3. You then
make middle =2.5 and want to figure out what your next guess will be after that.
All you ahve to do is figure out whether f(2.5) is < 0 or >0. You don't need to
find out the exact value.

we need to calculate f(.25) f(.75) f(1.25) f(1.75)
f(.25) = sin( pi/2) + 1 = 1
f(.75) = sin(1.5 pi) + 1 = 1
