1. Show that the partition function for a harmonic oscillator in the x direction only is given by: 9x exp(-ẞhy) 1-exp(-ẞhv) 2. Using your answer to part (1), derive the partition function for a single harmonic oscillator in three different directions. Briefly note any assumptions made. 3. Using your answer to part (2), show that the partition function for a crystal of n atoms (i.e., a collection of harmonic oscillators in three different directions) is given by: 3N exp(-ẞhv) Qays 1-exp(-ẞhv)
