Unfortunately, you can't differentiate with a calculator when the value of x is not given, but atleast you can use this to check if your results are correct
what if i just want to find dy/dx for a function, is that posssible on a calculater? for example can we type "2x^2"in a calculater to get the first derivative "4x""
why cant we do double differentiation in scientific calculator.....give us the tricks to solve this also.............its a humble request form me and my college friends.......please do something..
Of course different values of x return different results, you just need to make sure you use the same value from your result to the one on the calculator and they must match, if not then something is wrong in your solution. Let me know if I understood your point correctly

What if you just wunna get the equation without substituting an "X" value?
You cannot get the f(') equation, because this Casio does not return symbolic math solutions.
/Regards
At least you can check if your final simplification is correct or not!
ولا شو رايك
I could not see which buttons you press on the face of calculator, not informative.
We miss you please come back
Oh ,God just thank..It didnt match before as I didn't use rad mode in calc..thx very much for the information.
On some functions it gives math error, e.g. on derivating x^2 sec(4x) but the derivation is 2x sec4x(1 + 2xtan4x). It gives math error
This works best for MSQ
What if you want to get a square bracket??
Very clear, thank you.
Can you please tell any way to differentiate by using a calculator when the value of x is not given

There is too much of reflection that sometimes one cannot see what is written/typed on the screen. By the way, thanks.
V good
Thanks
Really helped me..
you cant just put any number as a value of x. try to input 4 and 6 to see the difference
Why won't you allow us to view the calculator sef
Nice 👌👌👌
wow

calculator doesn't work that way , it wont give you functions
you have check the value on both

thank you
how to put variable on constant value?
Arslan jappa you can press Alpha than press X as variable
@@ashrafulislam5811 how abt x square
@aaron rajadurai After pressing Alpha ,simply Press "X" [ in ( button ] ,then press ²(square) button
very helpful po.
How to solve y=1/loga^x dy/dx?
Bro!! It doesn't give the same value when you input any value for x... x=?
Of course different values of x return different results, you just need to make sure you use the same value from your result to the one on the calculator and they must match, if not then something is wrong in your solution.
Let me know if I understood your point correctly
You are wrong. Sir it's only two you can use
how to solve double differentiation using 991ES calculator.?
AFAQUE JAYA what did you mean by double deferentiation?
sorry
that time i little bit confused (if we dont know the value of x) now my doubt clear..

We can't seee please face casio to our side
Who the hell will tell where is log
Downvote; cannot see the calc inputs; shakey video. Bad.
thank you , for video
Isn't "ln" pronouced as lorn
lon, not lorn
