Wow thanks. Picking up where you left off: M2: (-1)•a+(1)•a D1: a(-1+1) A3: a•0 using additive inverse. Now I can use Theorem 1 that he proved or write it out: A2: a•0+0 A3: a•0+{a•0+[-(a•0)]} A4: (a•0+a•0)+[-(a•0)] D1: a•(0+0)+[-(a•0)] A2: a•0+[-(a•0)] A3: 0...

Thanks SammyS. Sigh.. I can't.. When I look at that I just think to Distribute it. (-1)•a+a=0 ... I just stare at it blankly. Can you give me another hint? Or do you know of a good reference I could read on this subject by any chance? I really appreciate your help. Thank you so much.

ok I think I'm on to something.. maybe? so lost so who knows. (-1)•a=-a line1: (-1)•a + -a + a axiom of additive inverse line2: -1•(a+a)+-a associative axiom line3: -1a+-1a+-a D1 line4: -a axiom of additive inverse again? Is that right? Can I...

Ouch, not the answer I was hoping for. Ok I didn't want to overwhelm you with text since giving all the necessary information is long enough, but here's what I've tried: line 1:(-1)•a line 2:a•(-1) line 3:a•(-1)•(-1)•1 line 4:(-1•1)•(a•1) line 5:-1•1•1•a+[a+(-a)] and then I go further down the...

Thanks in advance. 1st day at calculus teacher wants proofs. They seem rudimentary but I've never done them and he doesn't help so I'm hoping someone here could please. These are the axioms: Addition: For a, b, and c taken from the real numbers A1: a+b is a real number also (closure) A2...

Awesome, congrats on getting in. Yea, I agree with the CC, but the physics and engineering classes can be limited. Are you saying I should put in the 2 years and get an associates degree or put in about a year just to take some of transferable classes? I have an associates degree in marketing...

So a great resource is the collegeboard college match maker here: http://collegesearch.collegeboard.com/search/adv_typeofschool.jsp The search left me with 44 schools. Which I thought was around the perfect number to condsider. I went down the list and clicked on about half "add to my list"...

Maybe you don't want to start an essay on such a sad note.. and by maybe I mean most definitely.

and this thing we're having, although the subject has now changed from physics to the ability to discuss physics, is a discussion. Wouldn't you rather talk about physics than the inability to?

I disagree. There might as well not even be a forum then. Unless it's here to answer people's homework questions. forum |ˈfôrəm| 1 a place, meeting, or medium where ideas and views on a particular issue can be exchanged Ok easy to disprove this: How about books like Bill Bryson's A...

All I know is that motion is the natural state of matter, and that has something or everything to do with it.

One thing I heard last night at a lecture about degrees. The greeks, whom we tend to respect and use as our basis, used 360 degrees in a circle because they had a calendar of 360 days. Maybe the degrees don't matter as much as, why do the 3 angles in a triangle add up to a half circle? And a...

I'm going to find out.. I'll let you know tomorrow. (JOKE!)

Totally right Phinds, that was my point but perhaps poorly described. Just like there is no edge on earth, so is space/the universe... And again some people did think the Earth was flat/finite at one time which we just shake our heads at now. And that's a very thought provoking statement...

Hi, I really appreciate this and thanks for any help before hand. I'd like to start looking at schools and I'm having trouble even finding an idea where to start. I want to go back to school as a 27 year old transfer that was a college drop-out but did get an associates degree in a...
