All the legends who didn't study in 2020 & came here for annual exams😂😅
Update 1: I've FINALLY completed my 11th std annual exams with help of roshni mam💜
Update 2: completed school and currently studying in college,,,it was a long way tho but I'm happy that i made it through:)
Update 3: currently studying for semester exams, going to 2nd year next month , can't believe I'm getting older 🤧
Update 4: Worried sick for my future and looking for internships before I become a Final year student. I feel lost and I just wanna disappear at this point 🚶🏻♀️

But Roshni Mam: Toh chalo baccha party khatam karte hai yeh chapter 1 ghante me!!!!
Because roshini Mam is legend ...they know that we don't have time...lol 😂
Bro mam is just giving basic concepts so that we would be able to solve basic questions...and others use to give advance concept for higher problems
Just a few hours left for exam and I'm done with the video. Thanks ma'am, my words lack behind to express my gracious gratitude to you. I absolutely loved your explanation! ❤ But the only part I didn't understand was the 'Polar Form' as my basics of 'Trigonometric functions' isn't clear.
This video greatly helped me in my school exams as I didn't attend a single class of school.

Thank you mam !❤❤🎉🎉😊😊 5 Million toh hone chahiye
Mam, the way you express the topics, it's too interesting. Thank you mam now I don't feel like maths is not made for me.
Don't have words to explain your teaching... Just awesome😍
Your way of teaching is superb
I am watching your maths videos to teach my daughter who has appeared in std 10 in 2024. I am a 1998 batch commerce with maths CBSE and I suppose u must be junior to me too 😂. I have forgotten all concepts of Class 11 and Class 12 maths so I am watching your videos. And I must admit you are fantastic.The best thing about you is that you focus on pure concept and I truly praise you for your wonderful way of talking( I love it when you say "bacchalog" )and easy explanation of concepts.
I just watched your video on complex numbers and it was too good. But you missed one concept and I feel you should add it in your video of complex numbers---
Root 2 × root 3 = root 6 , for all real numbers
But ,
root-1×root -1 is not equal to root -1×-1
( why and how you can explain better than i can)
Also,
i^2=-1 and (-i)^2=-1
Therefore ,the root -1=i or -i , but for complex numbers we take i only .
Madam i think these two concepts are missing but necessary for proper conceptual understanding. Please also correct me if I am wrong.
Let me add again at the end that I am doing Maths after almost 25 years and your videos I find the best for those who want conceptual understanding.You are doing a great job.
Thanks and regards,
Saurav.

It is in the description
@@NarutoMaxTheRubanDemon did u care to check the description before commenting this?
we will always divide by 4
in i to the power 69
Maam For Q4 we can use and alternative method to solve as done by me , and we can get the same answer .The method i used was short as well as easy :
1)Write the same till you get a equation for (x-iy)(3+5i)= -6+24i
2) Solve the LHS equation and take the like terms all together we get : 3X+5Y+ i(5X-3Y) = -6 +24i
3) Use Comparing the Coefficients and form 2 equations as follows :
EQ 1 : 3X+5Y = -6
EQ2 : 5X-3Y=24
Now solving them simultaneously we get the values of X and Y as
X=3 , Y= -3
Thanks to youtube for giving this lovely video to recommend this channel and a very thanks to mam for solving our doubts.
