### Be an Optimist

"The pessimist sees difficulty in every opportunity. The optimist sees the opportunity in every difficulty."

Again, my first sentence have nothing to do with my scribe but I just don't know how to start.

First off, we reviewed continuity. You can say informally that functions are not continuous if you have to lift you pencil to draw them. The formal definition is:

• f(c) exist
• lim f(x) exists
• x-> c
• f(c) = lim f(x)
• x->c

After the short review, we did the test on limits. The class decided that we do this test like a pre test where we do it ourselves in 20 min. or so and then talk to our classmates about it. Personally I find it hard at first but I get it somehow after we talked.

Well like I said there is hope if we don't understand things. Look for opportunities and use them wisely.

The next scribe is.....
