oh god your right. Thanks. I should have just wrote it out without all the + and * nonsense and I would have seen that.

Homework Statement Convert f=(x'+y)(x+z)(y+z) from product of sums form, into the canonical product of sums. Homework Equations boolean logic, et al. The Attempt at a Solution This is boolean logic (so + is "or" and * is "and" etc..) There has to be some stupidly simple thing...

I'm writing something in Java, (but the language doesn't really matter for this problem), and I can't figure out any way to do this efficiently. I have some character array with a bunch of stuff in it, and I need to slice it into it's diagonals, for example: [a,b,c; d,e,f; g,h,i]...

Homework Statement I'm tasked with creating a logic network that can spell out a simple 4 letter word. It has 2 inputs A and B, and 7 outputs (for a 7 segment display). The 2 bits (A and B) give the 4 total possible inputs to the circuit. Write the truth table for the 7 output functions...

I've never heard of it before. Hilarious stuff.

I thought I would share this documentary about maths that I recently watched. http://vimeo.com/13497928

I don't think so. I took Physics 1 (mechanics etc..) and Physics 2 (Electricity, Magnetism etc..) with calculus, without having taken ANY physics in my entire life. Nor did I take geometry. I didn't have any problem with any of it, and I'm not terribly intelligent or anything. If you are...

Right now I'm well into my third year as a physics major and I'm starting to wonder whether or not it's for me. I really do enjoy studying physics, but I am starting to think that a more creative career choice would be beneficial to me. I have taken many language and programming courses for...

If your algebra and trig are good, this class will be no problem for you. The "geometry" involved is very intuitive. Any difficulty in the class will come from the physical principles, but that's what you are there to study in the first place. If you still aren't sure about whether you...

Move out. It's cheaper to live off campus anyway. You can rent a room or something, and then perhaps you won't be surrounded by 18 year olds 24 hours a day.

Yeah. That "add 0 to an equation by adding some quantity x and then subtracting x again" thing always catches me off guard. I'm very familiar with that trick from various calc II integrals, but it still always hits me like a truck.

Ah I see. So they are still playing the make one side look like the other game. Thanks again!

Homework Statement Prove that for every integer n>=8, there exists nonnegative integers a and b, such that n =3a+5b Homework Equations The Attempt at a Solution I'm trying to understand the proof of this. It goes as follows: I am having a hard time figuring out what is going...

Pickle as in "the tricky/complicated situation" ? For instance, "You're in quite the pickle!" ? /Yeah sorry about being AFK

I think I ended up doing something like that. My proof was basically this (I'm paraphrasing from memory)Proof: Assume that (0,100) has a cover consisting of a finite number of closed interval subsets. Let S be a collection of closed interval subsets of (0,100), such that...
