very snap way of finding the inverse of a two by two matrix
OpenStudy (anonymous):
in english, switch the element in the main diagonal, take the opposite of the other two divide by the determinant
OpenStudy (anonymous):
Shortcut method is to take the determinant first i.e 3*2 - 4*1 = 6 - 4 = 2 |dw:1340078218843:dw| May be I am wrong... Please confirm it..
