### Heisenberg Uncertainty Equation

When looking at problems that call for the Heisenberg uncertainty Equation, do we always solve for delta p (indeterminacy in momentum) first, because we are given the delta x (position), or does it just depend on what the question is asking for?

It really just depends on what the question is asking for. If it gives you the momentum (p), then solve for the uncertainty in position (x). And visa versa.

Problems will sometimes give the indeterminacy in position (delta x) and mass of the object and ask you to solve for delta v. This can be done because (delta p)=(delta v)*mass, so you can use the information you are given to calculate delta v.

The question will usually clarify which variable it is asking, so there is no particular sequence in solving such problems.
