The line current in a 3-phase delta loaded circuit is supposedly equal to sqrt(3) times the phase current. That's dependent on all the signals being sine waves though right? Because the math that gets you to that point is dependent on sine and cosine identities that don't necessarily hold with...

You assume that just by having a proof, the student will understand intuitively why a given relation is true, which in my experience has been absolutely false. Even if a student understands that dividing both sides of an equation by the same non-zero number preserves the equality, the question...

Nope, they taught us about Turing machines, but never about universal Turing machines.

What do you mean by "Completely uncomputable"? Do you mean that it cannot be computed for all Turing machines, that it cannot be computed for some Turing machines, or that it cannot be computed for a specific Turing machine? Because for a Turing machine without a rule to terminate, this...

I'm not following you. What does that have to do with 0.999... = 1? As I understand, that expression is confusing because notations involving an infinite number of components are unintuitive. And frankly, I see no reason why functions should not be represented as algorithms for the purpose of...

From elementary to high school I've had teachers who've droned on and on trying to explain minute details about the concepts they're teaching. I've almost always found it more difficult to follow the teacher's train of thought than to just learn the concept myself, so I always just read the...
