39well, elementary row transformations would help a lot. remember only row tranformations.
39well, its not the time for such things man. they come in engg 1st year.
well matrices wont leave us so soon.
1Also Gaussian Elimination
See an example here : http://www.mycoolaids.com/Determinant.aspx

1kalyan i didn't get ur method. will u please elaborate it.?
just tell me what's the final answer for the figure u plotted ! (in terms of A1 to D4)
1The final answer is........
(A1.B2.C3.D4)+(B1.C2.D3.A4)+(C1.D2.A3.B4)+(D1.A2.B3.C4)-(D1.C2.B3.A4)-(C1.B2.A3.D4)-(B1.A2.D3.C4)-(A1.D2.C3.B4)
You just extend the lines around the page,
ie., after ending the row, you go to...
#the first column of next row in blue
# last column of next row in red
1You cant say
i dnt think they'll ask this
wen it comes to JEE
They say derivative of second order and ask a question in seventh degree.
So Y not remember if U can???
