Question 23 (Writing the piecewise expression of a function)

(60)

Question 24 (Maple Function for vectors and matrices) (with(LinearAlgebra) needed)

(61)

But alot easier, type it like this and then copy the output and paste it directly into the answer field and it converts it into the relevant format:

(62)

(63)

Similarly with the matrix (which is just multiple columns or rows of the 'vec tors'), depending on ease, use either columns or rows (| or , respectively) to seperate them into the matrix

(64)

Question 25 (Analysing LinearAlgebra Package) a) The Maple function "RowOperation" from the LinearAlgebra package can be used to swap two rows of a Matrix M. Which of the following will swap rows 3 and 4 of  M?

(65)

 b) The Maple function "RowOperation" from the LinearAlgebra package can be used to mulitply one row of the Matrix M. Which of the following will multiply row 5 of M  by 2?

(66)

c) The Maple function "RowOperation" from the LinearAlgebra package can be used to add a multiple of one row of the Matrix M to another. Which of the following will replace row 5 of M by row 5 of M plus -4 times row 2 of M?

(67)

(68)

Question 26

(69)

Use Maple to create the vector vec tor b that is column 7 from A and the matrix C that is made from columns 1 to 6 and 8 to 9 of A (in the same order as the columns of A).  Now solve the matrix equation: Cx = b Correct Answer: 84491/659407 and enter the 7th component of the unique vector solution for x in the box below. (Your answer should be an exact fraction, not a decimal.) (Column is case-sensitive)

(70)

(SubMatrix is case-sensitive)

(71)

(LinearSolve is Case-sensitive)

(72)

Seventh Component is the 7th solution from the top

Use Maple to create the vector vec tor b that is column 6 from A and the matrix C that is made from columns 1 to 5 and 7 to 10 of A (in the same order as the columns of A).  Now solve the matrix equation dx = b and enter the 8th component of the unique vector solution for x in the box below.

(73)

(Column is case sensitive)

(74)

(SubMatrix is CaseSensitive)

(75)

(LinearSolve is CaseSensitive)

(76)

The 8th component is the value 8th from the top hence
