Why L'Hôpital's rule is not allowed in finding the limit six/x when x approaches 0
thank you! this help me a lottt!!! ❤❤but may i ask is there any solution when the expected value less than 5..? or it just applicable for expected value greater than 5
Hello. Yes, if the expected frequency in a Chi-square test is less than 5, it can cause issues with the validity of the test because the Chi-square distribution assumes that the expected frequency in each category is sufficiently large (usually 5 or more). When this condition is not met, it can lead to inaccurate results. Here are a few solutions to address this issue: 1. Combine Categories: If some categories have very low expected frequencies, you can try COMBINING adjacent categories to increase the expected frequency in each. This approach is often used in categorical data where grouping similar categories is meaningful. The method in this video is still applicable. 2. Use Fisher’s Exact Test: If the Chi-square test is not valid due to low expected frequencies, Fisher's Exact Test is a good alternative, especially for 2x2 tables. It calculates the exact probability of obtaining the observed distribution, so it doesn’t rely on large sample assumptions. Then the method in this video is no longer applicable since it involves different calculations. Hope this clarifies things. Thanks for watching. Wish you a wonderful day.
Very fast.. make it slow please
Hello! Thank you for your feedback. I try to maintain a pace that balances clarity and flow for most viewers.

how did you find that -6 20 14 -75 48 row?
Hello. Those numbers are obtained by using the synthetic division method. Thanks for watching. Wish you a wonderful day.
thank you sir
My pleasure. Thanks for watching. Wish you a wonderful day.
The answer is wrong . correct answer is 3-2root6/5
If you substitute both answers into the function, you'll find that mine works while the one you provided doesn't result in 0. It's important to be responsible and double-check before sharing answers, as the wrong one can be misleading. Feel free to verify with a calculator. I appreciate the engagement and hope this clears things up! Have a great day!
@ahsing_math NO SIR IN GOOGLE I HAVE SEARCHED OUT I GOT ANOTHER ONE SO I HAD SAD IT
Remove y, and the equation will now represent the entire universe. You're welcome 👍👍🤓🤓☯️🧬⚛️🦠💧🩸💫🌊🌈🌌🐟🐠🔄G🔄O🔄D🔄
No, even if you remove 'y', you still need to integrate both sides of d²y/dx² = 0. The result will not be 0. You're welcome.
why cant we use the de l’hospital rule?

All my matrices a,b,c are 3×3. I still get dim error while I try to multiply two matrices. My calculator was working fine all this time. But now I'm getting this dim error. Please help, I've got an exam tmw
Hello. Did you press MODE again when entering the second and third matrix? If yes, that’s the issue. The correct way is to directly press SHIFT → 4 and select 1 to define the matrix. Please note that this method applies to the fx-570/991MS model, as you're referring to this video. I hope this helps. Thank you for watching, and I wish you a wonderful day!
@ahsing_math no I didn't press mode each time. I could view the matrices in matA , matB and matC, but operations on it don't work
Really effective video ❤ thank you so much
My pleasure ❤️ Thanks for watching. Wish you a wonderful day.
Why multiplication in 9?
Hello! This can be proven. Consider 51 - 15. If I let x = 5 and y = 1, then 51 - 15 = (10x + y) - (10y + x) = 10x + y - 10y - x = 9x - 9y = 9(x - y). That's why we have 51 - 15 = 9(5 - 1) = 36. Therefore, regardless of what numbers we have, as long as they are in the form "ab - ba", the answer is always equal to 9(a - b). Thanks for watching, and I wish you a wonderful day.
Sir I have a 2.67 value for this the f distribution is 0.119 so how I can't find it in the table
Hello, The F-distribution table typically helps you find the critical value for a given significance level (α) and degrees of freedom. To find the p-value for a given F-statistic, we usually reverse the process: look up the F-value in the table to find the corresponding probability. However, if the F-value you're working with isn't directly available in the table, interpolation can be used to estimate the p-value. Keep in mind, this method might not be very accurate depending on the degrees of freedom involved. If statistical software or tools aren't allowed, and you're using a Casio calculator, I recommend this method ua-cam.com/video/zv_yzenTCVY/v-deo.html. It's a simple and efficient way to calculate the p-value. I hope that helps! Have a wonderful day!
Thank you
My pleasure. Thanks for watching. Wish you a wonderful day.

I have all other features except the" opt". Is there a way to solve without it
Hello! It depends on which model you're using. I’ve shared videos for three models (570/991MS, 570/991ES, and 570/991EX). You may want to check the videos list to find more details. Thanks for watching, and I hope you have a wonderful day!

bro electrical students will die if they do this , we almost have 10 minutes for a question . this calculation itself will take 10 min
Bro, that's why the saying 'practice makes perfect' exists. With enough practice, this can be done in 5 minutes, which is much faster than the conventional method that usually takes at least 15 minutes.
Can you do possion

how to do in fx-991 es plus
Hello! Unfortunately, the fx-991ES Plus doesn't have that function. However, you can use the factorization method (ua-cam.com/video/c7ULBNkmXnM/v-deo.html) or the Euclidean algorithm (ua-cam.com/video/DqCMITZiL3A/v-deo.html) to solve it with that calculator. I hope these methods help. Thanks for watching, and have a wonderful day!

In these types, if RHS=0, particular integral is also equal to zero Am I right ??
Hello. If RHS=0, the equation is a homogeneous second-order linear differential equation. In this case, there is no external forcing function, and you only need to find the complementary function (CF), which is the general solution to the homogeneous equation. Thanks for watching. Wish you a wonderful day.
