1. Systems of linear equations have a unique solution when the matrix A is nonsingular, i.e. when det(A) # 0. Consider the formula for the determinant of a 2 x 2 matrix. (a) What are two numerical issues introduced in Chapter 2 that may arise when computing this value? (b) Develop two matrices that suffer from these issues. Assume a floating point system that represents the mantissa with 3 digits
