Thank you so much for making such a comprehensive guide to using this calculator I had one doubt (maybe i missed in the video)
but in normal distribution if the sum has given us the probability value and we need to find the x value or the z value is there any way to do that or do we have to use normal tables

[@brianhenderson5117]

This guide is brilliant. Simply explained. Thank you so much. This is by far better than any manual. 😊

what a legend! Thank you so much.

[@equaser]

Glad it helped!

[@csimet]

Nice overview. While this calculator seems well rounded with many abilities, my biggest complaint is the choice of the case color and use of small colored key labels (above the keys). For us shade-blind folks, it can be very difficult to read the labels... especially the red and blue ones. The faux carbon fiber finish also contributes to making them hard to read under reflected light. A better choice for the case would have been white. It is still mostly usable and at only a cost of $15, I'll probably keep mine... but will be looking for another that is much easier to read.

[@Michael-mo4ol]

Woww, very great tutorial.. Thank you sir 👍👍

Great work
At 45:00 when you write derivative it must b d/dx instead of dy/dx because you have already written the function y..

At 30.39, if you want to convert decimal degrees to degrees minutes and seconds, type the decimal degrees and press the degrees / minutes / second button. Your input - output has to be in "Math Input - Math Output" for this to work.

[@akgh2010]

I really like your videos about different calculators and how to use them. A request here please. Can you do a Full manual to learn everything about TI-36 Pro. It's mandatory in USA and apparently your videos one of the best to explain everything about a specific calc. Thanks again for all your amazing efforts.

[@equaser]

I am pleased that you like them. In Shaa Allah I will try to make a full video for the mentioned calculator. But I have many videos on that calculator in small pieces.

You are welcome . I just posted the full manual with tones of example all features you will be surprised. Use chapter to jump czcams.com/video/wOwCf3Kd8-4/video.html must watch for 45 seconds to know how to watch

[@tanjil.ahmmed]

Just subscribed your amazing channel

[@julietzushi]

Great Video! Hope you can make a tutorial on how to use a stored value in an equation to find another unknown value (using Casio Classwiz). There seems to be no video tutorial for that on youtube.

[@equaser]

I have left nothing out If this calculator can do something, I have show it. There is a feature to find x value in any equation and I have show it. May be use the chapters to check it out or watch it fully.

[@tedsonkabiru4349]

thank you so much

[@rohitgs4593]

Sir one doubt.. is the ON button pressing feel different compared to other metallic button on upper sides of calculator... Please reply

[@equaser]

Cool.

[@roronoazoro3229]

Ive the same calculator and my calculator cover is loose from constantly playing with it in and out of the calculator on my boring classes so is there any way of fixing it?

[@destinyobamwonyi8865]

27:54 was not the rounding but the division of 100 by 15000 being calculated before adding 300 to the answer (BUDMAS).

[@わたしはなんと日本人です]

hi, I can’t reset the setting in setup > 1(input/output) > 3(line I / line0), it is always displayed M at the left top, and the fraction font is different

[@equaser]

You are most welcome

[@notreally-jc4xb]

Outstanding🤩🤩🤩

[@equaser]

we can't expect less from a Khorasani person.

[@pietrofavia7835]

Does exist a not graphing calculator that besides calculating derivatives and integrals in a specific point gives me an equation as a result ?
P.S: sorry for my ignorance...unlike me you are a true expert! Very few people on the net are so clear and professional in explaining , thank you so much !

[@equaser]

As for as I know, there is no small handheld device to do that. We need huge processing power to do it . Computer softwares such as MATLAB or Maple. Thanks for the comment.

[@KyriafinisBill]

You need a CAS calculator. The problem is that almost all (I was looking for this too and I have not found one since) CAS calculators are also graphing.

[@nirmalyachatterjee4724]

Thank you, Ahmed sir.

[@equaser]

You are most welcome

[@EliteMiko35]

I love this calculator

[@avantikarathore7003]

Hello Sir,
Is the ON button in this calculator a little lower than the rest of the keys? Is it a manufacturing defect or is done intentionally by the manufacturer?
Please clear my doubt.
Thank you.

[@equaser]

Hi, it is made so you recognize it without looking at it yo turn it ON or off

[@65pradyumna]

Does the matrix mode perform row echelon form and reduced row echelon form?

[@equaser]

This is full video manual. Everything has been demonstrated. So watch it.

[@zuhairabbas1712]

Thank you for covering everything in this video. This is the best calculator as of April 2021. Can you please tell me which is the best calculator now ( as of April 2022)?

[@equaser]

Still this is the best.

[@TheGayenur]

Is it possible to operate complex numbers in matrix mode in this model?

[@equaser]

No. I would have shown it. I have skipped nothing this calculator can do .

[@joelwong7929]

At 28:05 u typed 300+100 / 15000, when u were suppose to type 3000x100 / 15000 . Great video btw, very helpful : D

Good Day Sir!
I am planning to buy Casio Classwiz fx991ex but it seems like it now rare since Casio recently released fx991cw which is said to be an upgrade to the ex.
I find the fx991cw to be hard to used since Casio changes a lot in the buttons making it hard to learn.
Will you make a guide for Casio Classwiz fx991cw?
Thank you Sir

[@equaser]

I just searched for fx-991CW and could not find on sale. only Casio website shows it. Send me a link of a store if you know selling it online.

Thanks.

[@equaser]

I just check it seems old calculator and for this video I have spent almost a month to make it. I don’t think there would be enough demand with making this video. Or may be I am wrong. If I see it at local store beside sharp or Casio I will buy it and make the video .

[@worroSfOretsevraH]

​@@equaser They are actually very high regarded calculators among engineers. Best true RPN calculators made.
