The value of the theoretical density calculated for titanium can be calculated based on a rhomboidal arrangement, which represents one third of the compact hexagonal cell. Will the result obtained be valid for the complete or total compact hexagonal structure, which in total contains 6 atoms per unit cell? Explain your answer.In the Taylor Expansion, it looks like they've made x_0 = x_1, x_2 and made x = x_1 - a, x_2 - a. I don't understand how they can use that substitution for x_0 since it is a constant, and x_1 and x_2 are variables that can change.
