For #1b you must first find .
#2 is just a matter of doing all the caculations correctly.
hi, some more matrices problems that i can't solve
no 1 :
a) Find PQ which i did =
i can't solve b which is
b) Find a matrix X such that PX + Q = P
no2) If work out and
hence show that
i worked out x^2 and X^3 , and i tried doing the above calculations but didn't get x^3
what should i do?
thanks in advance
