### Effective Annual Rate

If the effective weekly rate is 0.12%, the effective annual rate is? The correct answer is 6.43%. How you get this value? Thank you in advance!!!

Hi vatso;

Experimentally, take a nice round figure of money like 100 dollars. Form the recurrence

with a(0) = 100 of course. Run it forward for 52 iterations, you get 106.43481. That is equal to an effective annual interest rate of 6.43 %.

Or use the formula

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
