A student writes twice:



	From **************** Sun Aug 30 16:53:30 2009
	Subject: Can I use the same output from one black 
	box twice as 2 inputs into another black box?

	<<No addressee>>

	Can I do this, or does the computer just recognize the inputs as one 
	input (I am trying to square the output from the first box by 
	multiplying it by itself in a second black box)?

	Thanks, looking forward to Monday's lecture.

	Subject: What is the maximum number of inputs a black box can contain?
	Date: Sun, 30 Aug 2009 17:58:01 -0400
	From: **************** 

	Is a black box restricted to only 2 inputs or can there be more?

Your email does not identify who you wish to read your message, and also isn't 
signed.  Is there some reason for that?

Second, did you read carefully the statement of the problem?  After you do, if 
you still have a question, I am happy to try to help.

Third, have you read the emails that I have already sent to the entire class?  
Is the answer to your question in any of them?

I am happy to answer your questions, but if I don't require you to meet me 
half way, then I am not really helping you to learn.

Good luck with the problem set and with EE 306.
