Warmup 1/12/16
When you accept Christ, are you saved no matter what?
Or is it possible to lose that salvation?
Objective
Tonight’s Homework
To learn a few more
properties of the definite
integral

Homework Help
Let’s spend the first 10 minutes of class going over any
problems with which you need help.
Notes on Definite Integral Properties
We’ve covered a number of things about the
definite integral (area under a curve). Today, we
want to summarize some of those rules.
b
b
b
∫a(f(x) + g(x)) dx = (∫af(x) dx) + ( ∫ag(x) dx)
b
b
a
∫ak f(x) dx = k ∫af(x) dx
b
∫a f(x) dx = 0
a
∫a f(x) dx = - ∫b f(x) dx
b
c
c
∫a f(x) dx +∫b f(x) dx = ∫a f(x) dx
If g(x) < f(x) on [a, b] then
b
b
∫ag(x) dx <∫af(x) dx
Group Practice
Look at the example problems on pages 298 and 300.
Make sure the examples make sense. Work through them
with a friend.
Then look at the homework tonight and see if there are
any problems you think will be hard. Now is the time to
ask a friend or the teacher for help!
