Question 1: Explain the process of summing elemental expansions/approximations using La- grange interpolation across each element and transforming this into a global expansion/approximation. Use a 3 element example with quadratic Lagrange interpolation across each element to illustrate the process. How many unknowns are there in the elemental expansion over the entire domain? How many unknowns are there in the global expansion over the entire domain? Question 2: Sketch the elemental and global approximating functions you described and used in Problem 1.
