    Graduate Understanding the Limitations of WKB Approximation in One-Dimensional Problems

    Hi all I have a question about WKB approximation Why is it that WKB method can be applied only to problems that are one dimensional or those which can be reduced to forms that are one dimensional ones? any help is deeply appreciated

    Is There a Mistake in My Proof for the Identity of Pauli Spin Matrices?

    Thanks Galileo for ur reply the results i used were\sigma_x\sigma_y=-\sigma_y\sigma_x=i\sigma_z i changed x,y,z cyclicly, and hence reached at 2i \sigma do u think I am supposed to get only i \sigma instead of 2i \sigma thanks in advance

    Is There a Mistake in My Proof for the Identity of Pauli Spin Matrices?

    Homework Statement prove the idendity \sigma \times \sigma =i \sigma where \sigma is Pauli Spin matrices Homework Equations The Attempt at a Solution This is how I did..and I am getting 2 i \sigma instead of i\sigma ...
