Finally a video that explains difference in features between 991EX and 991ES instead stating differences in their looks, solar cell or display. Keep up the good work sir.
Thank you. I've recently bought this model, and I'm trying to teach myself how to use it. It is so much faster than the fx991 ES when doing integration.
I am a Math teacher and I really loved the new cool features explained by Sujoy Krishna Das............Cool guy.....!!!!
make more videos on 991 ex classwiz please !!!!!!!! i have this calculator, i want to learn it as early as possible!!!!
+Avishek Maji I definitely will! Meanwhile you can watch my tutorials on 991ES. They both have most of features common. Link- goo.gl/uiTDQS

Does the F991EX have GCD and LCM ? Thanks in advance !
The Insert feature, and Random integer (e.g. dice) are also available on the fx-991ES PLUS.
+Crazytesseract Insert and Random number generator is there. But Dice, i.e RanInt is not in 991es.

+Sujoy Krishna Das I was speaking about fx-991ES PLUS, the updated model of 991ES.

The fx-115ES PLUS has more features than the fx-991ES PLUS, including RanInt.
Hello Sujoy sir,
I have problems in this equation solve
x(Cube)-2x(Square)-4x+8=0
But when i am going to solve this equation on my calculator it give me only X1 and X2 value why it don't give me the X3 value??????
Please help me and give the solution for this problems.
#Online To The Brain Do it without a calculator.
I know Aam and i can do it my self but that is not my problems my problems is why this eqn can't solve the calculator i mean why it dosen't give us the thiird variable ?????
I know Aam and i can do it my self but that is not my problems my problems is why this eqn can't solve the calculator i mean why it dosen't give us the thiird variable ?????
I know you might've figured it out now but when solved the equation only has 2 answers which is why the calculator is only giving you 2 answers. I'm guessing this is what Amam Danilowicz was hinting at. If your answers were x=2 and -2 then your calculator is correct as the root 2 is a repeated solution meaning that the one of the turning points on the graph lies on the x axis.
Ah yes, cubic graphs can sometimes hit at only 2 points.
Is this a programmable calculator?
No
@@satyeshprabhu3513 thanks!
Can we calculate the Polar and Rectangular calculations and Martix and Vector calculations on Casio Fx991Ex?

Is it a programmable calculator? Is it allowed in btech semester exams?
Casio calls it non-programmable. In my terms, it's Semi Programmable. In WBUT sem exams it's allowed. IDK about other boards.

please tell what is the use of the button represented by ( - ) on the calculator.
+Niraj Bind That's for putting minus (-) sign representing negative number. Subscribe to my CZcams channel so that when I upload a new video,you get notified. If you like any of my videos,I'd request you to please like & share it. Because sharing is caring :)
+Sujoy Krishna Das Thanks for your answer.
But i don't see the use of this button because all the operations that could be performed by this button can easily be performed using the regular minus button.
+Niraj Bind exactly, but I think there is one function where only the (-) works... and I cannot remember what it is!
+Niraj Bind Anyway there is one case where there is a difference. Suppose you calculate 5+2=7, and then want to continue with minus(Ans) * 3 = minus 21 (ie minus (7) *3= minus 21). After the first calculation you cannot use the [ - ] key to enter minus(Ans), because the calc will take it as Ans (minus) ... so you have to use the [( - )] key to enter minus(Ans).
+Crazytesseract Thanks
nice
How to erase the STO value(A in this case)?

Learn proper english pronunciation first. Its a shame if u pronounce 'shame' like 'same'
knowing a language properly is also a part of knowledge. little learning can be a S(h)ameful thing for an idiot like, u know. so it doesn't suit u bragging about knowledge. first enlighten your precious knowledge storage.
Cant believe idiots like you still exist! and my dear friend he is not here to explain you English he is here to explain how to properly use a calculator
Right
Before this , all of you butterfucks learn to grammartical phase something.
