Hey All, I've just started reading a discrete math book, and in the beginning the book covers logic. One concept I'm finding hard to understand is certain conditional propositions. When the example uses a word problem, I mostly get it. The statement is "If The Mathematics Department...

Great! Thanks for the info. Steve.

Hey All, I'm learning calculus through videos. The videos that I'm watching are really good, but they are deficient in power series, taylor and mclaurin series, binomial series, and taylor polynomial applications. Anyone know where I can see video instruction for these? Steve

Hey All, Is there a software package that shows a step by step how it solved a problem? I've looked into Maple, and I think that Maple does this, but not sure. I'm looking for software that will help me learn calculus, analysis, linear and abstract algebra. Also, does anyone know about...

What the heck is a+1=1/a? I can't get an answer. I get to (a squared + a)=1, then I'm stuck. Steve

tyrizzle, Don't worry about starting low. You have 4 years. Taking a couple of remedial math courses is no big deal. In a year, you'll be taking Calculus, so don't worry about it. Steve

Thanks Edgardo.

Hey All, I'm starting to learn proofs. Is there a good website that starts with the simplest proofs, and goes from there? I've googled this, but thought maybe some of you may know something that isn't easily found. I can also get books from Ohio State, so maybe some book suggestions...

Thanks for the info, both of you. Steve

Thanks for the reply. I"ll check on what you suggested. BTW, Is there a software program that makes posting math symbols easier? Maybe a graphics program where I can just post an image? Thanks, Steve

Hey All, I found this proof on the internet, but its logic seems flawed. Let x = (-a)(-b) =(-1 * a)(-1 * b) =-1 * a * -1 * b =-1 * -1 * a * b =(-1 * -1)(a * b) = ab So it's saying that (-a)(-b) = ab. This doesn't seem like a logical proof, or at...

Hello all, I'm in Calculus 2, and I was given a problem for bonus points, which I desperately need. It has to do with the best place to sit in a movie theatre. The problem is long, and has a diagram, so I've attached an image of the problem to this post. I have no real clue where to...

I'm not sure if this is what Disinterested knowledge means, but it makes me think of knowledge that no one is interested in. If that's the case, you can't ever be interested in it. Once interested, it ceases to be "Disinterested knowledge". So, does it even exist? Lol. Steve

I think it would be funny if you wrote your name on a piece of paper, and just handed that in. "I have a name, I exist" type of thing. And, I don't think that you can "prove" that you exist. The thing that I hate about these classes is that even though there are no real answers to these...

Compuchip, Thanks for the reply. You're right about my confusion about understanding dimensions. I'm going to ask one of my teachers to explain dimensions to me on a blackboard. Is this a problem that I should ask a physics teacher to explain, or a math teacher? Is there a point in math...
