Some help with P-Chem

hello all,

I am doing some homework and need some verification on the math:

[Px, Px^2]f= PxPx^2f - Px^2Pxf

Px= -iÄ§d/dx
Px2= -i^2Ä§^2d^2/dx^2

-iÄ§d/dx(-i^2Ä§^2d^2/dx^2f) - (-i^2Ä§^2d^2/dx^2)( -iÄ§d/dxf)

i^3Ä§^3d/dx(d^2f/dx^2) - i^3Ä§^3 d^2/dx^2(df/dx)

the number following the "^" sign just means raised to that power. Would someone verify if this is correct please? thank you.

Hi,
Sorry to be the bearer of bad news, but this is not a homework help forum. We assist students with projects for science fairs.
Good luck.
Chris
