- To calculate RMS value of any function, we first square it, then find the mean value over some time period, and finally take the square root of it. Since sine and sin squared functions are both symmetrical about their centers, we can calculate their mean value without using calculus. Let's explore how.

The most surprising thing is how underrated this channel is. Sir your videos are so ingenious. They are just perfect 👍👍❤️
It's so easy to understand when you have a good teacher. Thank you for this
If I'm not able to understand during my physics lecture, I'm totally relieved because this guy here will make me understand everything and even better. Pure GEM.
Damn... That is more intuitive that doing integrals. You sir, have blown my mind :-)
Its amazing to learn from such teachers.
Just so smooth and crystal clear!!
ok that was mind-blowing, wow...
Thank God I have seen this beautiful person ❤❤🇵🇰
bro made physics easy. I mean not even my school teacher or my tutor can teach me in that way. bro should be saved , but genuinely thenks for making concepts of physics so easy .
Hey hacker where u learned this method...🙂🙂🙂 I loved it!!!
The best explanation of RMS value. I always wondered what is the process to get RMS value. Thank you for letting me know.
OMG this was cool. The only video I found that properly derives RMS. Thank you for making this video!1
Me after learning all videos of this channel Booyah! Centum
Something beautiful explanation
Sure, your use of color was superbly masterful. I taught math for several years and always used it in my formulas and its can make things that much more apparent. Thank you, sir!
sir just wanted to tell you you are a reallly awesome teacher
I don't understand why this amazing video got dislikes
Pure genius!
Great explanation brother
omg I thought the accent was a sign of bad teaching.... u know usually in college, professors with accent most of time aren't good (not every one). But he's definitely one of the exceptions, especially for his passion! Great job!!
This channel is so underrated
Hats down for you, though you could've just said it was 0.5 - 0.5*cos(2wt) and taken av of that, av of 0.5*cos(2wt) is zero and av of 0.5 is just 0.5, 0.5 - 0 = 0.5
mind blowing explanation sir
Thanks for the awesome presentation sir💗
wow..amazing
I want your short introduction..pls pls
Exquisite ❤
Thank you sir 🙏
Mahesh is Walter Levin of our time.I think he is more than him to me.
Sir in your description box you mention 'reused allowed '. What do you mean sir ? Did you mean other can reuse or re upload your video in youtube ?
yup bro , they are like a sort of charitable company working to revolutionize the world education system and have no reason to not allow others to copy them ,the more people educated the better
Damn!!!!Where you learned this method🤩🤩🤩🤩🤩🤩
Wow
❤
O-so-intuitive 🙃😁
Pls sir atomic physics
😂 "without calculus" so relatable 😂😂
It is easy if you are using calculus
If you know calculus*
