Yes, I think you're right. I think I am talking nonsense. If two irrational numbers (or even their generating functions) add to form a rational, then by definition those numbers (or functions) are mirrors. So how did I get sucked down this road? I guess, I wanted someone to come up with an...
That's right, but the irrationality of y derives from the irrationality of x (or vice versa) so both x & y have the same irrationality. I'm asking whether two independent irrational numbers can ever add to make a rational.
Thinking about it, I'm sure there are no examples. Because for a...
Obviously one can create the "mirror" to an irrational number which itself is irrational and add these two irrationals to get a rational: e.g. pi and (4-pi) are both irrational and add together to make the rational number 4. However, I would call this a trivial solution because the second...
Thanks for the equation. Is there a way to visualize this using a 3D space-time diagram (as opposed to a 4D diagram which would a little difficult to draw ;))?
Can someone with a bigger brain than me please explain this situation:
You've got 3 people A, B, & C. B is in the middle and A & C move away from him in opposite directions at 2/3 the speed of light as seen by B. What speed is C going from the perspective of A and why?
...and see if you can help me find the equation for the volume of the toroidal section shown. Perhaps the double integral at the end of the first post is a better proposition. Any pointers would be much appreciated. Thanks :)
