2a. Confirm that the position and momentum, p=-ℏ ∂/∂x, operators do not commute. 2b. Show how the statement above limits the ability for a state that to be both an eigenstate of position and momentum concurrently. 2c. For an eigenstate where the momentum is zero, show that x than p leads to a result, xp, that is different than that of p then x.

Not all operators are commutative, namely, a*b = b*a. Consider functions under the operators addition, subtraction, multiplication, division, and composition. Pick two of the functions and use a grapher (like Desmos) to graph the functions under the operators. If the functions are commutative under the operator, the graphs should be identical (overlap everywhere) when you change the order in which the functions are entered with the operator. Determine which operators seem to the commutative and which operators seem not to...
