Re: Orthogonal Functions Question

(0,1) is orthogonal to (1,0) and (1/2, 0) but (1,0) is not orthogonal to (1/2, 0). You can't compare vectors transitively to check for orthogonality; it isn't an equivalence relation. The first part of what you said is right; orthogonality isn't a transitive relation. The second part of what you sa...

Re: Orthogonal Functions Question

Whether or not to vectors(in this case functions) are orthogonal depends entirely on your choice of inner product. In the space defined by that inner product those two vectors actually are orthogonal.

Orthogonality isn't necessarily transitive.

Re: "increased by 400%"

My pet peeve is exponential growth. You always hear the talking heads on the news saying that something is "growing exponentially." I would just love to corner one of these tv news types and say: Oh, really? Can you tell me what that means? To most people it just means, "growing real...

Re: Ohio Computer Science Undergraduate Research Conferences

There's the MCURCSM(Midstates Conference for Undergraduate Research in CS and Math):

I'm also interested in similar opportunities to present undergraduate research. Anywhere in the US is good.

Re: Could someone explain this to me? (continuous function)

Hint: For the two functions to be continuous, seeing that they're both independently continuous, they only need to agree at the point they "join" at (x = 0)

Re: Grad school for comp sci?

Both of you have said you have to pay for school at the masters level but I've found several schools offer assistantships to masters students that pay for tuition as well as a living stipend, am I missing something?

Re: 0816: "Applied Math"

Um, I haven't studied this much, but it seems obvious to me that you can prove a system of logic to be inconsistent. Take ordinary logic and add the axiom "P ^ ~P". Done. No? That'll just prove that your extended system of logic is inconsistent, not your starting system :( I just meant th...
