Yes but what about the primes that are larger than the primes that went into it but still smaller than number in question. I know 2311 is prime, but there are still many primes larger than 7 but less than 2311. Maybe eventually there is somewhere that it breaks down, then again maybe it won't...
I was discussing something with my friends today. If you take the product of the first n primes and add 1 will this give you a prime number?
For instance:
2*3 +1 = 7 ------> prime
2*3*5 +1 = 31 -------> prime
2*3*5*7 + 1 = 2311 ------> prime
Can anybody find if/where this breaks...
2 equations, 2 unknowns
Use:
x=rcos(theta) eqn. 1
y=rsin(theta) eqn. 2
Since you know what x and theta are you can solve for r in eqn. 1.
Then once you know r you can plug that into eqn. 2 and solve for y.
