Question 28309: Give examples of the following matrices:
2x2 identity matrix I2x2(the 2x2 is smaller then the I when written)
5x5 zero matrix 0 5x5
Two non zero matrices A and B such that AB=02x2
A 2x2 matrix C such that C does not = I2x2 but C 2(squared)=I2x2

check my answers....i am rusty on matrices:

I%5B2x2%5D = %28matrix%282%2C2%2C%0D%0A1%2C0%2C%0D%0A0%2C1%29+%29

M%5B5x5%5D =


A = %28matrix%282%2C2%2C%0D%0A1%2C1%2C%0D%0A1%2C1%29+%29
B = %28matrix%282%2C2%2C%0D%0A-1%2C1%2C%0D%0A1%2C-1%29+%29

C = %28matrix%282%2C2%2C%0D%0A-1%2C1%2C%0D%0A1%2C-1%29+%29
