It is also known as (*) unity and the sum of an event's probability and that probability of its complement equals this.
The Collatz conjecture concerns whether the sequence given by a certain function always reaches this number. The single element of the trivial multiplicative group is written as this. A nth of unity is a number that when raised to the nth power equals this. It is also known as (*) unity and the sum of an event's probability and that probability of its complement equals this. Sine equals this at pi over two. This number is the multiplicative identity. For 10 points, name this whole number that comes directly after zero.
