I don't ever comment on anything. But the quote at the end made me. It was different but in a good way - I really liked it. Video was quick and useful too. Thanks!
In calculating a determinant with cofactors (multiplicating numbers on first row here) and minors (the smaller 4 number determinant) , you need to alternate signs from left to right on rows and up down on columns (if you were to use a column instead of row).
why did you do - the second number in the first row then + the third number in the first row? is that the rule? first number (on first row) - second number (on first row) + third number (on first row)

Very quick and simple. Understanding Triple Scalar Product the night before the final :P
Thanks a lot! I love your videos. No one explains like you! Wish you were my maths lecturer!
Thank you so much for all the videos you do. They're a huge help and I can't thank you enough.
How come the second set is a minus negative 4, but it is addition for the third set?
sir @Mathispower4u could you kindly explain this?
It is the rule for solving 3×3 determinant you have to add 1st and 3rd set while 2nd set has to be subtracted.

Thank you for the nice comment!

@NguyenEmpir3
swapping the rows will change the determinant....you have to be very careful
This video is perfect, thank you so much!
Another great explanation. Thanks!
for the better
this was so helpful thank you
Should show the 3x3 shortcut method for those who don't know it.
Great video. Thanks
Thank you, I like the quote at the end!
thank you
thanks for the help!
Thanks was helpful
thank you so so much!!!!
a bigger man
nice video:D
THANKS!
Thank youuuuuu
you've changed me
thanks baby
it helps me to find out Calculate the scalartripleproductu·(v×w),
gotta love fp3 haha
i am a new man
thank you
