h/2pi, How does this play a part in Heisenber's Equation?

Dr. Lavelle brought up h/2pi, which he referred to as hbar, after stating Heisenberg's Indeterminacy (Uncertainty) Equation.
I don't understand how it plays a role to Heisenberg's equation. Where did h/2pi come from? And is there a certain time you use h/2pi instead of h/4pi?

To the best of my understanding, hbar is equal to h/2pi. Therefore, hbar/2 can be rewritten as (h/2pi)x(1/2), which when multiplied out is equal to h/4pi. When Heisenberg's equation mentions h/4pi, it is simply another way to write out hbar/2 in an easier to understand format.
