Thank you, taught me a couple of things! Just want to add that there's a shorter way to check if you've got the correct X value. Just click TRACE right to the left of the GRAPH button and hit the suggested X value, it will then tell you the corresponding Y value 😉
@@stevenscottoddballz Fancy seeing a new comment here but I gotta add that not everyone cares about grammar, especially not in a youtube video's comment section about a calculator.
So how would one graph -5x^3+35x^2-45x-25>0 on a TI-83 Plus? We've entered it into "Y=" every which way and don't get anything close to what the textbook shows we should have seen. Help!
This is beyond the scope of this video but you would go to the far left of your y= after putting in y=0 and hit enter until it shows shading above the y= then you would enter the long equation part in the y= for the 2nd equation and go to the far left and move it until it is shaded below the y=. This will give you two shaded regions and the answer is the shaded part in the overlap. I don't have the time for doing another video but hope this helps.
I wanted to use the Quadratic Equation to solve: [8S^2 + 6S = -5]. I got the final answer of: -3 [+-] i [times the Square Root of] 31 [ALL over] 8. I got my calculator out & entered: "(-3+i[Square Root](31))/8" Then it gave me the answer of: [-.375+.69597054...] I have never seen the Plus Sign in an answer. What does that mean?
What a relief to find somebody who can teach a fool like me.

Such a great video. You're an awesome teacher. Thank you so much for sharing!
Thank you for taking your time to create this tutorial
Thank you so much! This was so easy to understand :)
Window, limits of. Y. Limits of X. Horizontal lines of X, virticles of Y. 180=H. 90=V. Zenith..
Very useful. I just found my calculator from high school
you should really work on your handwriting; and you have 2 minutes of material spanned over 20 minutes, maybe try not being so slow
you are such a boring speaker. its like your putting yourself too sleep. other than that good video
You need to learn English. You have "...your putting yourself too...", when it should be "...you're putting yourself to..."

this is math lmao

@@stevenscottoddballz Huh ?
Oh my goodness you WONDERFUL WOMAN!!!👏👏👏👏👏👏 THANK YOU SO VERY MUCH!!! Keep these videos coming please you really helped me out!
i was absent for this lesson and it helped me so much; thank you!
Y= likey. Forms of expression,read it on graphics print,plus paper likey too..
Great vedio. Your great professor. Thank you very much indeed.
The calculator isn't completely on the screen, so her functions aren't visible.

No, it's not a perfectly put-together lesson is it, but still, I learned a lot of useful stuff from it!
@@helenday5031 yessir
Trace key. ? Love the key, quick values.
SPD,times. Moments=pnts.
2019?
very helpful. thank you!!!!!!
When I changed My window I almost Got the same answer... yet I learned something new today
Window ymin=-22?
In India they give us a graph sheet or we use formula for this.
No use of calculator for high school.
agreed
do you want a cookie?
Thank you 🙏
Thank you...
Had been away from the subject for a while. This was a great review... 👍👏👍

Thank you I think I finally understand this!!

ik this is an old comment but… its in a+bi form, a and b being -.375 and .69597054
