    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

    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.

    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.
