A particle can be described by the following normalized wavefunction in the region x=0 to X=2L : (x)=L1cos(2Lx) Calculate the average position for the particle over that region. You will need the following integral solution: xcos2(ax)dx=41x2+4a1xsin(2ax)+8a21cos(2ax)+C 2. Write down the integrals you would need to solve to determine the average momentum for the particle in Problem 1. (You do NOT need to solve the integrals.)
