8*[[3,-1],[-4,2]]

Verify that [AB]^T =B^TA^T where A=[[1,2,3],[6,7,8],[6,-3,4]] B=[[1,2,3],[3,4,2],[5,6,1]] .

The range of the following data is -------- -6,-8,3,2,1,4,2,5

Show that the points (4,7,8),(2,3,4),(-1,-2,1) ,(1,2,5) are the vertices of a paralelogram.

Show that the points (4,7,8),(2,3,4),(-1,-2,1) ,(1,2,5) are the vertices of a paralelogram.

If the points (8,1),(3,-4),(2,p) are collinear, prove that p+5=0

Show that the points (4,7,8),(2,3,4),(-1,-2,1),(1,2,5) are the vertices of a parallelogram,but not a rectangle.

If A=[(4, 3, 1), (2, 3, -8), (1, 0, -4)], B=[(2, 3, 4), (1, 9, 2), (-7, 1, -1)], C=[(8, 3, 4), (1, -2, 3), (2, 4, -1)] then verify that A+(B+C)=(A+B)+c

If A = [(6,-7, 8),(1,-3,1),(2,1,-4)] , compute det (adj A).
