[Casio fx-115ES (plus)] Solving System of Equations, EIT, FE exam Prep

[@watertriton]

I’m glad I didn’t know my Calculator did this when I was Learning. but I am happy that it can. Thanks for sharing this video.

[@icecold153ify]

This video was just what I was looking for. Straight to the point and no prolonged intro!

[@englishman32257]

I have just recieved my Casio fx 991 Plus, thank for posting these videos, very help full.

[@kory1221B]

This video save me on my statics test today. Your instruction was awesome Thank a lot

[@kory1221B]

*saved

[@TheMetalButcher]

@@kory1221B It was nice of your statics professor to not do a 4x4 like mine did.... My casio did not save me on that one. xD

[@pdbass169]

Thank you so much for the helpful tutorial. You have a real talent for explaining and teaching. I can't wait to learn more from your videos.

[@esmashahin2167]

thank you! it's hard finding good videos for casio's, you're awesome

[@Wmann]

I’ve had this calculator for ages and I didn’t know this. Thank you so much, thank goodness I thought to myself “Hmm I don’t know much about this calculator, I’m gonna look it up”

[@vuruvwzlksz]

OH MY GOD THANK YOU MAN, i found out how to do this on my graphing calculator, but then my teacher said we cant use our graphing calc for the test, i was worried

[@hopefulmelancholy7514]

Thanks,man I can understand you so much better than my professor with her "Masters in math".🙄She may have a Masters in Math but her personality is really bossy etc. Plus she is one of those lazy professors that forces her Students to use MathXL. I wish everything wasn't so rushed in class.I keep you on my watch later playlist so hopefully I pass Intermediate Algebra this time.I'm in community college and the tutoring centers are mostly open during working hours. You're a great tutor. 👏📚📖😁🙌

[@kieranpat]

Wow this is a throwback video, still helpful!!

[@rosalyna.6620]

THANK YOU SOO MUCH!! I bought this calculator because of the modes but I didn't knew how to properly use it and it's potential.This video was very helpful. 😊

[@YuriSoul2222]

I enjoyed the sound of your voice and you gave very good instruction. Very pleasant video to watch thank you my friend

[@Kayy_SS]

I wish I could give this video 10 likes, or I could subscribe it one more time. I picked this same calculator at Walmart for my engineering class ( I am a type of person who don't believe that I can only work things out with expensive calculators), but I gave up after a few times trying to find where to put system of equations, literally until now. Thanks a lot, man. Now I am back to a happy engineering student with a $15 calculator.

[@MrPsimmons3]

Thank you VERY much for this excellent tutorial!!! VERY well done!

[@reandra38]

At Last! A simple but very effective video!

[@blackpenredpen]

Thank you! I also have made another video a few months ago, kzbin.info/www/bejne/bHfOhIBvZt9po6M hope you can get more out from this calculator! : )

[@reandra38]

do you have a video using fractions that contain ex: 7x/3-x=x/27-8/9

[@amysmith8432]

very cool those problems take a very long time to work out manually I have this calculator yeah I hope I can learn this and problem solving just got way faster thank you

[@michellegarcia7738]

Very helpful video! When I have multiple pens/pencils, I actually do the exact same thing as you!

[@pneujai]

Oh hey I just bought this calculator and searched it up on youtube, 謝謝曹老師

[@blackpenredpen]

My top 5 reasons of getting this! kzbin.info/www/bejne/bHfOhIBvZt9po6M

[@Upper_Room_Studios]

Great job! I have the same calculator... and also the same pens!LOL!!! If you ever do a tutorial for the Casio Classpad II 400, let me know! Keep up the good work. :D

[@kyliesmommy84]

Thank you..truly. I appreciate this video

[@EngineeringEducation]

Excellent video!! I highly recommend this calculator.

[@jefejeffwell1113]

Huge help, brotha!

[@carmaster1693]

Hi blackpenredpen do you have playlist of video where i can found all of your videos about this casio calculator

[@proudomani]

Thanks, excellent job.

[@smalltugz]

i found this calculator at my school last year i never knew it could do this kind of questions

[@fabiansoto7307]

Really good explained

[@EnduredX]

Thanks man. I wish I knew how to use the calc better on my last test.

[@blackpenredpen]

You're welcome

[@hanna5514]

Thank you so much for this video! It is marvelously helpful.

[@optimusprimo]

THANK YOU! Can this calculator perform larger matrices than 3X4??

[@harshitshirsat4127]

What could be the reason for MATH ERROR , in the above type of question but for some different equations

[@mitchd1311]

How can you solve a system of equations with the unknowns being inside a trig function with this calculator without making substitutions? ex. -208.87cos(x)+y=0 and 248.9sin(x)+y=311.04

[@dchambers986]

Can you show a review of the TI 30x vs 36x?

[@jasminecarter9594]

Thank you so much ! You are fantastic

[@yarieskicasas5486]

Is it possible to find, using the calculator fx 115es plus, the gradient, divergence and curl of a vector? thank you

[@jdriver75]

How do I store results from MODE 5:EQN? Say I solve a cubic equation and get 3 results for x. Sometime they're not displayed in simplified fashion, ie 1.414213562 instead of sqrt2. I'd like to use the S-D button there but it doesn't work. so the other solution is to copy an answer, go into MODE1:COMP and convert it there. But I can't figure out how to store the answer. Thanks.

[@mrzombiesbo]

Should have learned this a long time ago lol, didn't realize it was this easy

[@MyrtleBeachWebAngel]

Thank you so much. This was very helpful to me!

[@s13rr4buf3]

Very helpful, thanks!

[@coolcat1058]

How would you graph those equations on the calculator? Ex: x-y=3 X+y=5

[@amadiohassan3354]

It's really helpful thanks alot❤️

[@eselman7363]

THANK YOU SO MUCH, YOU ARE SO AWESOME!!!

[@blackpenredpen]

you're welcome!!

[@ianwong5470]

Hello, Just bought this calculator for school. Was wondering if it is capable of solving more than 3 equations with 3 unknowns, like 6 equations and 6 variables.

[@cesaraugustoalbahacamendoz9147]

Good video. Thanks

[@tori7894]

thank you so much very helpful video!

[@agovics1]

Ty for all, is there a way that it solves a^x?????

[@thabang2949]

dope video man

[@florencequintana3092]

Wow your video really helped me...Thanks!!!

[@likeos2135]

I have used your videos getting ready for the Fundamentals of Engineering Exam... we are a huge market for your videos, add 'EIT' or 'FE exam' to the titles of your videos so others find you as well. Good videos, thanks!

[@blackpenredpen]

+likeos Thank you for the suggestion! I just added those keywords to my video. Best of luck on your FE exam

[@Killer97]

omg lol saaaaaaaame

[@hjjjhh5774]

Thank you!

[@Unfiltered_scene]

thanks my brother . it was helpfull

[@user-df3qe9cb3c]

Omg this was so helpful thank you!!

[@TheMetalButcher]

So no way to do a 3x4 other than craymers rule huh? God I need a ti-89. Also, I like your dual pen setup.

[@johnredorn]

Thank you so much

[@emlmm88]

It's great, but unless you have a _lot_ of equations, it might just be quicker to do the Gauss-Jordan elimination by hand.

[@rachelward2005]

🎉thank you!!!!

[@mbgames1007]

omg thank you so much! you r a life saver

[@tecengcivil]

Ola muito boa sua aula

[@RPS_Capital]

[@crusher7070]

Thanks bro helped alot

[@McScubakis]

Thank you this helped alot

[@livinguntohim1]

Thanks!!

[@SimplyPinoyNotSoRichRico]

WTF! whats the point of creating calculators if the teacher won't let me use it to solve these! "you gotta show work" what the heck, i just hate doing the work!!! Thanks mate good video

[@aoeronin9574]

Just do the initial work and get answer with calcand write down the answer, you should be fine

[@Killer97]

the point is these are for saving time not doing your work for you math courses require you to knnow these things but in other courses you can save time by using a calculator

[@nicolenc2140]

Thanks!!! :)

[@tombardier]

informative video, thank you. (but the music can be a bit maddening!)

[@sohailjanjua123]

Hi I like your video

[@polypoly4400]

Ans/0.1 how to solve

[@john-athancrow4169]

Its like 1.3 eh?

[@dayrongarcia2604]

Is there a way to solve trigonometric definite integral using this calculator?? Thanks in advanced.

[@cydget644]

I'm back. Kate will accept vitamins.

[@who6284]

[@zehraali5156]

Very bad writing ohhhh

[@aoeronin9574]
