... xth square number when you know the value of y. In contrast, the recursive formula for the square numbers is an = an - 1 + 2n - 1 where a1 = 1. To find the nth square number, you first need to find the previous n - 1 square numbers. Other examples: • The linear function y = 60x + 230, which describe ...

... For all other positive integers the value of Carmichael’s function is the least common multiple of all the dividing primes raised to the appropriate powers (e.g., to calculate ψ(504) we’d reckon ψ(23 ), ψ(32 ) and ψ(7) and find the LCM of these). Sequence A002322 in Sloane’s OEIS gives values of ψ(n ...

... How can I decide from a graph whether it is a function? The vertical line test is a way to determine whether or not we have a function. If a vertical line intersects the graph in more than one place, then it is NOT a function. The test is simply a restatement of the definition of a function which st ...
