how do u do this on a scientific calculator? i cant find the rref button

[gdawgrapper]

@lifeDotGov I don't know of any scientific calculators that will do matrices. I'm sure there must be some, but I am unaware of any. Maybe you can do a search with your model of calculator entered. Thanks for viewing and commenting.

@gdawgrapper my calculator has matrix mode.. i figured out how to edit and store matricies but can't figure out how to make it simplify it into the diagonal 0 thing o_o.. if it has matrix mode it must be able to do this? SHARP brand el-w516x

Thank you so much for this video! I missed the lesson on Matrix yesterday and you just saved me hours of stress!

[KlariRIOT]

WOoooooo thanks!!! I know how to solve the ones with 3 equations but ugh it takes too long and I get so frustrated. I have a final tomorrow and calculators are allowed and you saved my butt! Thank you so much for the video! :)

thx!!!!

[SilentQ]

Thank you so much, you just made my life allot easier :)

When i have to check you said hit 3 -> Storage -> X but where do i find the x and y???

[gdawgrapper]

@SilentQ I'm not sure I understand your question, but at 5:52, look at the two numbers circled in red. The one on top is the x value, 3, and the one on the bottom is the y value, negative 2. So those are your coordinates for your answer, (3, -2). Those are the numbers you check on your testing. On the other video you commented on, the background music is related to the subject, but I agree that it's too loud and distracts. Thanks for viewing and commenting.

[gdawgrapper]

@donovanfonseca Thanks. But don't forget other ways too since you might be tested without being able to use a calculator. Thanks for viewing and commenting.
