一開頭嘅尖叫聲係咩事😨

diu my classmate cleared my cal gei have to enter again

[@looplove8559]

同感

[@feanorasia0414]

Relatable

[@Ballymuncher]

Real I feel you

[@laikenus8752]

Thx bro, really helped in my G8 final exam

[@justyaoi4808]

Thankyou so much for teaching how to put the program because I need it for my maths DSE which is tomorrow

[@paolo5B1]

Life saver, thank you very much for this Video

[@TizedesCsaba]

Thanks for your program, but more straightforward and convenient, if you write the equations in the following form: A×X + B×Y = E C×X + D×Y = F And must to check the determinant is not zero, before you calculate the solution. ...ahh, OK, but this calculator has only 6+1 variables (A, B, C, D, X, Y, M). In this case you can use the variables in this form: A×x + B×y = X C×x + D×y = Y more easy to remember to the "structure".

[@chericiu]

in this program, seeing "Math error" means that the determinant is zero.

[@TizedesCsaba]

@@chericiu OK, thanks.

[@anson7466]

"問號"可以直接咁"EXE"

[@dynpallomah5918]

睇你打程式真係痛苦 ? 可以撳 prog 1 （應該話 shift 3 可以簡化成 prog） -> 可以直接 shift rcl [var name] : 撳 exe

[@chericiu]

thanks! 我當年拍的時候未知 XD

[@huzefashan]

4:35 why did my answer came in negative? It came as -79 over 13 ?

[@anson7466]

其實直接咁"prog"呢個button就可以搵到"?","＞",etc

[@chericiu]

咦, 係喎! 多謝你提供有用資料!

[@user-jf3fs9bj5t]

數學堂用到！非常感謝教程~

[@ncp31kit]

我按了mode 6 and 3 跟住應該咁咩掣去delete

[@flickonYT]

How to delete a program that you programmed?? Can you tell me what button to press please?

[@chericiu]

you can press Mode - 6 - 3 (then choose which one you want to delete)

[@flickonYT]

@@chericiu Thx

[@mandychan3274]

請問這個prog是Ax+Bx+C=0還是Ax+By=D？

[@chericiu]

Ax + By = D

[@5b14cheungyantung4]

Do you have the programs suggest us must be enter for DSE Math?Thank you~

[@chericiu]

no definite answers indeed. This program (simultaneous equations) is a must. Aiming for 5+, maybe "Intersection between line and circle", "4 centres of triangle", "3 points find circle", ... Reference: dsemathinfo.com/recommendedprogram/ Aiming for 2+, maybe "finding angle by cosine formula", "completing the square / finding vertex", "solving cubic equations"

[@gregaustin5533]

fx-5800p or this ?

[@chericiu]

the syntax in fx-5800p should be quite different

[@gregaustin5533]

Eric Chiu Does it have equation solver ? and also, Can you store formulas ?. thank for the reply btw

[@chericiu]

I'm sorry I am not knowledgeable enough to answer this. I did not try fx-5800p before. Perhaps you may check P.104 of this document: support.casio.com/pdf/004/fx-5800P_E.pdf

[@gregaustin5533]

Eric Chiu sorry for the confusion what i meant was the calculator that you are using :) , I am an HP user. it has a function that lets you store formulas and solve for the the unknown variable.Can you do it on fx-50fh, thanks you earned a sub.

[@yiumelody4894]

你好，如果系計simultaneois equation y=x-1 y=x^2-7x+6 甘x^2可以用你教ge program 嗎

[@chericiu]

我這個 program 只適用於兩條 linear. 如果一條 linear, 一條 quadratic. 可以參考呢個 program: webcal.freetzi.com/casio.fx-50FH/simultaneous5.htm 我相信 3650 P II 應該都 work

[@younoobergaming5932]

想問下 如果a b c d有分數計唔計到?

[@chericiu]

一樣係咁入, 沒問題的

[@supertennis8711]

@@chericiu ok

[@lady_ip]

Thanks a lot!!!!!!

[@yiumelody4894]

hi, 想問可唔可以做quadratic equation--- 3650p 2

[@yiumelody4894]

quadratic equation 條programme,網上沒有3650p2

[@mgueelveris]

does exists a program to calculate simultaneous equations with 3 unknows??

[@chericiu]

the program would be very complicated. I could only provide a link with the program, but the explanation about the program is in Chinese. webcal.freetzi.com/casio.fx-50FH/simultaneous4.htm If you try it, you have to be careful because you will need to enter the "REG LIN" mode when you edit the program.

[@mgueelveris]

oh, I understand. Thank you very much!

[@mgueelveris]

I tried, but it did not work, even with the REG Lin mode. I think that must be the model of calculator, mine is a fx3650p.

[@chericiu]

You may try this: webcal.freetzi.com/3650P/simultaneous3.htm

[@mgueelveris]

Eric Chiu Now it worked!! Thank you so much man. No words 😆

[@aestelle9930]

份數應該點撳？

[@chericiu]

the "a b/c" button (第二行第一粒) 例如: 3/4 按 3 "a b/c" 4

[@AlfredHanderson]

點解正負會調轉咗？

[@chericiu]

邊度有調轉？

[@huzefashan]

@@chericiu mine came as negative so I had to change it to positive

[@Bernardo96]

Does the calculator remain with the programs after you turn it down? Or it erases everything?

[@chericiu]

The programs remain. Don't worry. =] (Just be careful do not press shift-9-3 EXE, everything will be gone if you do so.)

[@Bernardo96]

Thank you for the answer! Greetings from Brazil!

[@debbielaw1277]

我想問吓入咗program，但係個數撳出嚟係錯嘅可以點做？

[@chericiu]

冇乜理由喎，check 下有冇入錯
