It is recommended that the assignment be done in Mathematica in its entirety and turned in electronically on the MIT Server. 1. Mathematica practice problems . Write a Mathematica notebook containing the following items: (a) A header in a text cell containing the Homework assignment num- ber and your name. If possible try to use a Style Sheet of your choice in your Mathematica notebooks from now on. (b) (Not for grade) Multiplication of a 3 3 matrix by a 3 1 vector. Choose arbitrary symbols (not numerical values) as matrix and vector coecients. Repeat for coecients with arbitrary numeric values. Repeat one more time for the case of a 5 5 matrix A and a 5 1 vector v whose coecients satisfy the following functional dependence on the row ( i ) and column ( j ) number: A ij = i + j...
