Format:
• Enter your solution as a matrix or a column vector, using the
vector/matrix palette tool.
• When entering an augmented matrix, do not include any divider before
the final column, i.e. input (Ab) rather than (Ab).
•
If no solution exists, enter the single character "n" (without the quote
marks).
• Enter your answers exactly (without rounding), i.e. input rather than
.
