This silly little calculator brought my average grade up by 30%...
But it is very time consuming right? I like the ex more unfortunately it's replaced by cw
I got my grade up
70 to 98
My calculator is not working this way.... equal sign is not coming even after pressing bracket sign after shift button 😭
If you input a quadratic how do you get the second value for x?
You hit equal second time or you can press the down key.
Edit: I thought you were talking about the dedicated quadratic solver. Well yes, when you type in a quadratic and hit solve the calculator asks you to put a guess value. It starts at your guess value to work out the solution closest to that guess value. To get both solutions (one at a time) you can first put a very negative number e.g -50 this will return the root having smaller value. You can then put a very positive value e.g +50 to get the root of larger value.
Hello Sir, can this calculator perform the solve function with derivatives or integrals present? Such as solving for when a derivative equals 0? Thanks
Yes you can but it is in the silver mode in Equation now, rather than calculate. Hopefully video soon.
@@TheCalculatorGuide Thank you for the swift answer! Would you happen to have any knowledge on the Casio fx-JP900CW, the Japanese version of the Casio fx-991CW? I am curious as the whether or not the Japanese version has an English mode - I know the Casio fx-JP900 (Japanese version of Casio fx-991EX) has an English mode. I am interested as I hear the Japanese models have a periodic table, among other features.
Hello sir, can you please explain how to solve equations that have more than one root, thank you
To solve a polynomials for example x^2+2x-3=0 (roots are 1 and -3)you type it in and hit solve. The calculator asks you to input a 'guess value' and works out the solution closest to guess value. Let's say you input -10 in first try, the calculator starts at -10 and gives the nearest solution x= -3 Then you input +10 in 2nd try and therefore get the nearest solution x=1. In summary you input a very negative and very positive guess value to get multiple solutions.
is there a way to convert the answer you get from the solver from decimal form to fraction
The answer derived in solver is stored in the variable (let's say you got a solution of x=4.765) You can go back to Calculate and recall the variable i.e input an x on the screen and hit equal and now you can use format to change it like usual.
when i press ON or HOME or if the calculator is off, all calculation history is gone. Is there anyway to keep the calculation history?
it's really helpful
Why is my equal sign not working
I raced you on my 991 es and I got the solution even before you could get to the solver mode. See who's the real boss
This is an app, he's using a mouse cursor
Of course it's gonna be slower genius
You missed my point Mr. Brilliant. Even he used a physical version of the calculator I can easily race him and solve it faster in my 991 ES plus that's because the Es plus is easy to use doesn't require you to change modes to solve an equation (Unless the equation is time consuming to solve at which point he will have an advantage of better processer speed)
Can you do an inecuation?
I am not sure what you mean?
It does not have an nCr button?
It is in a menu now. Video soon.
THIS IS SO FREAKING IRRITATING. Why can't I just put an = while in the calculate app like the ex? Is there any way to find x while being in the calculate app?
Huhu me too
Simulator link?
You need to buy a calculator first. You get a code to access this from Casio’s classpad site
Casio have stated there should be a web version soon though
@@TheCalculatorGuide Where's the form?
@@TheCalculatorGuideTell me more
No S->D?
No it’s FORMAT now
@@TheCalculatorGuideHello can i convert fraction or decimals into scientific as quickly as possible without clicking the format button and then selecting?
You can press SHIFT then = for decimal, but not for scientific I’m afraid.
@@TheCalculatorGuide That's the problem. I am already getting decimal answers as default but i want it in fraction
@@dhruboshahriar3959 Try number format in the setup menu and change to MATHI/MATHO
