Basic Math - Graphing with a Ti-83 or Ti-84 Calculator

In this video I take the Ti-84 graphing calculator and show you the basics of how to graph equations. Specifically I cover how to:
store equations
adjust the window size
view the graph
trace or evaluate points.

my professor posted this online on canvas as a resource to help us better understand how to use this confusing mathematical gadget lol Extremely helpful, thank you so much

"now we get the equation, looks great"
Me: wtf I have weird ass lines

You sir have just saved me oodles of frustration on my math exam. I am beyond thankful that it is easy to use.

Just ordered one with my birthday money. Trying to do equations on my TI-30Xa makes me want to jump off a cliff.

Wow, this video was very helpful. I have never used one of these calculators before and it is a requirement for my Math class this semester. Naturally I looked to YouTube for a video on how to use it and found yours. I feel much better that I know how to use it a bit. Thank you!

Required to have this in high school, got through college with a basic scientific calculator 🤷‍♂️

To make an x/y table, after graphing, press 2nd and then graph. There’s a little button that says table above graph.

Thanks, this video helped a lot

This video helps A TON, I have STAAR test tomorrow and I just know how to use a graphing calculator, I have not use an graphing due to I am a online student and now I am completely clueless about how to use it. Thanks for the help!

If people are having trouble with the ERR:DIM MISMATCH, it can be fixed by clearing all other y = and deselecting all plots (they will be in a black box and you can deselect it by pressing enter on it).

This video was uploaded 7 years ago but it helped me A LOT OMG THANKS

Pro tip: use the (-) below the 3 instead of the - to make negative numbers.

Oh my gods, I actually know how to use my calculator now! Thank you math man!

[heythere]

Thank you so much! This was so helpful. I was having a really hard time with learning how to use this calculator.

"1:Quit"

I'm back in college for the second time in my life. First time I was 18, I am now 35 😅 and in algebra 150. I didn't even pass algebra in high school... I think you just became my new best friend.

This video explained this better that my Algebra 2 teacher did. Thanks

[deadly_john]

Haven't used this calculator in a while, I'm about to do my ACT and this was a great video! Thanks :)

I’m in my 40s and I still use the same Ti-83 calculator I had since college!
