Please could someone help me with this question, thank you.
Find dim[Ker(D^2 -D: P_3(F_3) ==>P_3(F_3))]
Where dim is dimension, Ker is kernal
D is the matrix
0100
0020
0003
0000
D^2 is the derivative of D is it equals
0020
0006
0000
0000
And F_3 is the field subscript3
so D^2 -D
Should equal
0220
0010
0000
0000
But where do I go from here? I have tried reducing this matrix to row echelon form however this doesn't seem logical, do you have any ideas on finding the dimension of the kernal?
THANK YOU
