Re: Teach David

That is a really big list. It has 1000000 numbers in it. You can not see it because the ; at the end of the command suppresses the output to the gui.

How do we add that list up?

Re: Teach David

We use the built in command called Total. Just go Total[a] and you will add up all the numbers in the list called a. What did you get?

Re: Teach David

That is the sum of throwing 1 million die. What is the average?

Re: Teach David

That is really close to the exact answer of 3.5

Re: Teach David

Not exactly. What we did is called running a simulation. By actually throwing the die and counting them up we found an answer that was very close to the correct answer.

Re: Teach David

I know, not very exciting at the moment but we will build on this simple idea to solve much more complicated problems in the future. By the way, this is called experimental mathematics.

Re: Teach David

Let us say that we have

A = {1,2,3,4,5} and B = {11,2,6,7,0}. If we wanted to add them we would just go A + B. Try it.

You can also make one using sliders.

Hi; I know how to make parabolas in gebra now. Perhaps we will learn the sliders method once we're done with what we're learning with m at the moment.
Talk to you soon. I have a serious case of abdominal pain.
