  • 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.

    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.

    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 .

    The best explanation of RMS value. I always wondered what is the process to get RMS value. Thank you for letting me know.

    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!

    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!!

    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

    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 ?
