We talked in class about an example of an iterative calculation - radioactive decay. Starting with some amount of U, we know that each billion years we lose a fraction alpha, that is,. To predict U n , we start with U 1 and iteratively multiply by the factor 1-alpha. In this case, we have a formula predicting U n from U 1 , so we can just use the exponentiation function - we know how to take the nth power of some factor. In general, iterative calculations don't admit closed-form expressions for the nth step in terms of the first. But there's another way to do the calculation - using the for loop.
