Have som problem solving this problems in MATHEMATICAL METHODS 2.
Can someone help me solve and
explain this problems?
Problem 2. Find the values of the parameters a and p for which the system x+5y = 6, has: (i) a unique solution, (ii) infinitely many solutions, (iii) no solutions. Hint: Use the following fact: a system with as many unknowns as equations has a unique solution if and only if its coefficient matrix is invertible. See Lecture 22 and Homework 8 for examples
Problem 4. Compute the determinants below. In order to reduce the amount of calculations, try to choose the most suitable method for each determinant. 1 0 0 1 2 3 (iii) 1 4 5 1 3 6 1 0 45 (0 0 5 4 (0 2 6 31 (iv) 1 0 1

Let A e Rmxn. The linear system Ax = b can have either: (i) a unique solution, (ii) no solution, or (iii) infinitely many solutions. If A is square and invertible, there is a unique solution, which can be written as x = A-'b. The concept of pseudoinverse seeks to generalise this idea to non-square matrices and to cases (ii) and (iii). Taking case (ii) of an inconsistent linear system, we may solve the normal equations AT Ar = Ab...
