    Correction : At 20:26 I made a mistake for the trigonometric identity involving Sin2x. It should be
    Cos2x = 1 - 2(Sinx)^2
    or, (Sinx)^2 = (1 - Cos2x)/2
    FORTUNATELY, the final integration result (and normalization constant) came out to be exactly the same... So final result is correct. Uff :D

      Comes from a chemistry with a lots of doubt on quantum chemistry the lecture was awesome doubt was clear and thank you again for the fluent English as i hardly knew or understand hindi thank you again appreciate so much bro

    If not for Our Indian brethren what would we have been.
    Most of our lecturers make us to run to RUclips videos like this for help. And great you've done a very great Job Man. God bless you for us here in Nigeria ❤

    This was an amazing video sir. I think it will be really helpful to students if you created a whole series of quantum mechanics, based on Griffiths. Prof. Brant Carlson has already made a course on YT, but I think that too lacks a certain rigour in explanation of complicated problems.

    @preranadash9640 4 года назад

    Sir, as the particle is moving inside the box then it must have some energy and if we some how calculate it's energy then we can calculate corresponding wave function. And if we are unable to calculate its energy then also it has some specific energy which is constant but it's wave function is linear superposition of all the above mentioned wave function.Sir, Can you please clear my doubts ;)
    And thankyou sir all your videos are the BEST.
