Matrix Questions

Expand or collapse the matrix to the correct size and enter the correct values for each matrix element.
Expandable matrix question

Questions with a matrix require you to provide an answer in matrix or vector format.

Note If the matrix is expandable, you determine the number of boxes, rows, and columns for the correct answer. The default number of answer boxes shown is not necessarily the number of the answer boxes for the correct answer. You can modify the number of answer boxes by clicking the:
  • right arrow to increase the number of columns
  • left arrow to decrease the number of columns
  • down arrow to increase the number of rows
  • up arrow to decrease the number of rows
  1. If the matrix is expandable, increase or decrease the number of columns and rows until you have the minimum number of answer boxes necessary to provide your answer.
    It is possible you might have more boxes than your answer requires. If so, only type in the boxes you need to provide your answer and leave the extra boxes blank.
  2. Type your answer into the answer boxes.
  3. Click Submit Answer or Submit Assignment depending on the submission options for the assignment.
