Hmmm....this got me to wondering if it would be possible to make a real life Tron game with GPS systems...

Anyone more knowledgeable about GPS systems want to weigh in on this idea?

### Re: Question About the Probability of Test Answers

Good lord, I seem to have opened up a whole can of worms here.

This isn't really helping me =(

### Question About the Probability of Test Answers

I thought up this problem and I can't seem to figure out which is correct, so maybe someone here could help me out. Suppose you had a sufficiently large multiple choice test, like 200 questions or so, with answer choices a,b,c,d, all randomly chosen. Suppose that you were 100% confident in all your ...

### Help on an integral...

I need to find the integral of 1 / (4 - 5sin(x)).

Our teacher says it can be done with something that has to do with Weierstrass, then a partial fraction. I've googled all over and can't find anything related to this type of integral and Weierstrass, could someone help me out?

### Re: Math question problem...

Wow...how did you think to use that?

More generally, how do you learn techniques like that? I mean, being a high school student, I obviously understand substitution, but I would never have thought to do a substitution like that.

Does it just come with doing lots of problems?

### Math question problem...

Solve this system for x and y x^2 + y^2 = 130 and ((The cube root of x+y) - (The cube root of x-y)) / ((The cube root of x+y) + (The cube root of x-y)) = 3 Been stuck on this problem for a while...any hints? The first equation is a circle, but I have no idea how to simplify the second one into a usa...

v(theta) = v1 + mgrsin(theta)?

I have no idea what your getting at here =(

### A Conservation of Energy/Kinematics problem.

http://img505.imageshack.us/img505/5849/29366767kn2.gif OK. I've been stuck on this for a while. There is a ball of mass m on a string being swung in a vertical circle. At the top, there is a speed v1, and when it swings to the second place, it has speed v2. The only force on it is gravity. At the ...

### Can this number exist?

Can there be a number that contains every possible permutation of digits in its entirety? You would think you could so something like 0-9 and keep adding them on to the end, but what about infinitely long sequences? Would the number be in another category of infinity? What about irrational numbers i...
