How do mathematicians figure out the numerical values of sines and cosines? I can figure out how to evaluate sin(pi/12), sin(pi/24), sin(pi/48), etc, using sin(pi/6) and half angle formulas. How would I find sin(pi/5), for example? Is there any way other than infinite sums to express the...
[SOLVED] A twist on the twin paradox, help me figure this out!
Relativity question:
A twist on the twin paradox (that again??) Yes, that again.
First, it took me a while to accept that the acceleration breaks the symmetry of special relativity and accounts for the difference in aging of...
