Is this what the problem is?

#3 Re: Jokes » Poem by a student » Today 04:26:47

It is like my feet are stuck in cement.

#4 Re: Help Me ! » How to name a plane » Today 04:23:09

What kind of plane? The one that flies or the one in geometry or the tool?

For the one that flies over my house all night long:

Do not be an old stick-in-the-mud.

#6 Re: Jokes » Poem by a student » Today 04:03:24

You have the sisyphean task of rolling that big boulder.

#7 Re: Jokes » Poem by a student » Today 03:59:03

Let he who is without sin cast the first stone.

#8 Re: Help Me ! » Sin,Cos, Tan, Sec, Csc, Cot. » Today 03:03:13

Hi;

7) is incorrect. Use SOHCAHTOA.

8) is incorrect use SOHCAHTOA.

9) Use SOHCAHTOA, in this case tan(x) = opposite / adjacent. Can you fill it in?

Before we go any further some things have to be put in your memory banks.

1) Pythagorean theorem.

2) SOHCAHTOA.

Hi;

Post them whenever you like.

#10 Re: Jokes » Poem by a student » Today 02:52:43

Yes but people who live in glass houses should not throw stones.

#12 Re: Exercises » Bitter die » Yesterday 13:45:36

Let me know what you get and thanks for working on the problem.

#13 Re: Exercises » Bitter die » Yesterday 13:40:30

No, I just copied his.

#14 Re: Exercises » Bitter die » Yesterday 13:33:31

Yea, I think I will stick with his linearity principle on this one.

#15 Re: Exercises » Bitter die » Yesterday 13:31:05

Maybe, I do not remember offhand.

#16 Re: Exercises » Bitter die » Yesterday 13:17:44

Maybe you could do it but I do not know how?!

#17 Re: Exercises » Bitter die » Yesterday 13:01:31

Okay, I spoke to soon. The Markov chain gets the expected time to when the event occurs not how many are expected to happen.

#18 Re: Exercises » Bitter die » Yesterday 12:51:39

What are your headings?

#19 Re: Exercises » Bitter die » Yesterday 12:33:44

You have the matrix? Then please post it and we will see...

#20 Re: Exercises » Bitter die » Yesterday 12:30:05

For the first part you will create the matrix in M compatible form.

#21 Re: Exercises » Bitter die » Yesterday 12:22:48

You could ask a great computational mathematician. A guy who consistently gets answer when everyone else fails. A guy who has mastered both Mathematics and Mathematica and a dit of Maple too. Or you could try asking me.

#22 Re: Exercises » Bitter die » Yesterday 12:17:04

Well there is an easy way to find out.

#23 Re: Exercises » Bitter die » Yesterday 12:10:19

That can be done with M or by hand.

#24 Re: Exercises » Bitter die » Yesterday 12:05:09

It can also be done using a Markov Chain and therefore a recurrence and a generating function.

#25 Re: Exercises » Bitter die » Yesterday 12:00:06

I saw a post outlining a nice method, so I posted the problem.
