Prove that the product of matrix [cos20 cos0sin0 (below dis)cos0sin0 sin20] & [cos2alpha cosalphasinalpha (below dis)cosalphasinalpha sin20] is a null matrix where 0 & alpha diffre by an odd multiple of pie / 2.
i m nt able to get anytng of ths concept plzz hepl :(
If A is a square matrix such that A2 = A. Show that :-
(I + A)3 = 7A + I
if AB r 2 matrices AB=B BA=A then A^2+B^2=
prove that
a2+b2/c c c
a b2+c2/a a
b b c2 +a2 = 4abc
find the value of X and Y..if 2X+3Y=[ 2 3 , 4 0 ] (2x2 matrix) and 3X+2Y=[ 2 -2 , -1 5 ] (2x2 matrix).
if A and B are symmetric matrices, then ABA is
a-symmetric
b-skew-symmetric
c-diagonal
d-scalar
1. Using matrix method, solve the following system of equations :
2/x + 3/y + 10/z = 4, 4/x - 6/y + 5/z = 1, 6/x + 9/y - 20/z = 2
2. For what value of x, the matrix [5-x x+1
2 4 ] is singular?
there are two families M and N . there are 2 men , 2 women, and 4 childern in family N . and 4 men , 6 women and 2 children in family M . there commended daily allowance for calories is child : 1800, women : 1900 and man : 2400 and for protiens is man :55gm, woman : 45gm and child :33gm. using matrices algebra, calculate the total requirement of protiens and calories for each of the famlies ?
Ten students were selected from a school on the basis of values for giving awards and were divided into three groups. The first group comprises hard workers,the second group has honest and law abiding students and the third group consists vigilant and obedient students. Double the number of students of the first group added to the number in the second group gives 13, while the combined strength of first and second group is 4 times that of the third group. Find the number of students in each group.
Give an example of two non-zero 2x2 matrix A and B. such that AB=0
if A is any square matrix then prove that
AAT is symmetric?
If A = (aij) is a 2 x 3 matrix and aij = i+j, write down the matrix completely.
There are two families A and B. There are 2 men 3 women and 1 child in the family A and 1 man 1 woman and 2 children are there in family B. The recommended daily allowance of calories is men 2400, women 1900, and children 1800. Represent the above data in matrix form...
Here how can we put into matrix form and please post answer with explaination... Please experts...:)
