In this tutorial, you will learn how to solve equations using the "Numeric Solver" function on the TI-84 Plus CE graphing calculator. I go over how to solve basic equations, equations with multiple solutions, and the limitations of this program.

A very helpful video that gave me the help I needed in the first 30 secs!!! It was handy to skip forward to the limitations too :)

Thanks man, Im floating between a C and B in calc right now, and my tests are only a few questions, so this is literally a difference between a pass or a fail

How can I do this on a ti-84 plus? My solver doesn't have the E1 and E2 box.

@Ky-vv8nj Год назад

It's because you're not using mathprint. Press [ mode ], at the top, change it from CLASSIC to MATHPRINT. It will work after that.

@sb2h 10 месяцев назад

Yes you can. If there's just one place for you to enter the equation with x= directly below it, you need to set your equation = to zero (ie: 2x=4 becomes 2x-4=0) and it will solve for x

@rockopaws1610 9 месяцев назад

Is there not a way to get both values of x? Older calculators can do that

@colinb8952 4 месяца назад

is there a way to use this to find complex roots?

@leeprimeroessler3277 3 года назад

Just bought my first ti-84. I have to say this solver is crappy compared to the hp’s and casio’s. It acctually can’t display both solutions from an second degree?

@GoodLife_TV 4 года назад

Just a tip folks, you can use the X symbol for another other letter other then the X on the TI-84 Plus CE.

How I have a ti 84 plus ce and can't figure out how

@GoodLife_TV 2 года назад

@@liamperry1306 Hello, Perry! Should be labeled on the calculator.

@Avighna Год назад

2:30 ah yes, the wonders of newton-raphson. Or atleast, I’m guessing that’s how it solves equations.

ohhhhhh

@23StudiosSports Год назад

Why would they make the graph button the solve button fml

@jessiemayfield6749 Год назад

I’m sorry what? You’ll press graph again and it’ll tell you x=1/3 then quit. I got e1-e2=0 no x value!

@cheekymonkeygirl3378 6 месяцев назад

Omg, who has a team for that? I love algebra. I do it myself anyway. Not worth the hassle. 😢

@guloguloguy 2 года назад

your explanation is fair, but, your fingers click around way too fast, and it's impossible to see what keys you are choosing...show the entire keyboard, and, keep your hand out of the way!!! [use only one finger, or, a pencil!]

I get the wrong answer here with my TI-84 Plus CE-T -2(5c - 10) + 16 = 4(2 + c) Answer should be c=2 but it the calculator gives the wrong answer. I checked my inputs 4 times and I filled in everything correctly. When I use c it says c=0 when I use x instead of c it says x=-0.3030303
