[@handle-4-19]

Your explanation is gold. Take your medal 🏅.

[@Greenemath]

Wow, thanks!

[@benjamingiosis4880]

absolute legend, cheers homi, Explained the reason for the positioning. I love you

[@Greenemath]

Glad the video was helpful!

[@minugigunawardana8600]

my jaw dropped when you did that short cut for finding determinant for 3x3 matrice

[@Greenemath]

That is a very common shortcut and one you should definitely learn. I would suggest watching the lessons in order as we covered this in the lesson on determinants for a 3 x 3 matrix.

@@Greenemath do you have a video on graphing and solving the volume of a paralellepiped?

[@Greenemath]

@@AljomarJularbal Not currently, I am still working on my trig course. Krista King has a video on the subject if you want to used vectors:

[@ToptechCompany]

please what are you using to teach. it looks very easy

You can use any drawing app you want. If you have Windows, you can use Microsoft One Note.

[@iconci48]

thank you sir for making this video

[@Greenemath]

Most welcome

[@helloig5686]

What if your not given one x coordinate but they given you the area

[@Greenemath]

Just set it up with the formula and solve for the unknown.
