2+Delta=(-1,1)" find "quad A times AA

Evaluate : (-1/2) times (-1/2 ) times ( -1/2 ) times (-1/2) times (-1/2 ) times ( -1/2 )

In a Delta ABC,a=4,b=3 and the medians AA_(1) and BB_(1), are muttally perpendicular,then square of area of the Delta ABC is equal to

If A = {:[(3,2),(1,1)] , find a and b for which A^2 + aA + bI = O

If the coordinates of the mid-points of the sides of a triangle are (1,1),(2,-3) and (3,4), find the vertices of the triangle.

For the matrix A=[{:(,3,2),(,1,1):}] Find a & b so that A^(2)+aA+bI=0 . Hence find A^(-1)

For the matrix A=[{:(,3,2),(,1,1):}] Find a & b so that A^(2)+aA+bI=0 . Hence find A^(-1)

IF the coordinates of the midpoints of the sides of a triangle are (1, 2), (0, -1), and (2,-1), find vertices of triangle.
