    Thanks for the explanation sir. Your videos are really helpful.
    In qstn , (D^2 - 2D +3)y = cos 2x , first it should be (D^2 - 2D -3)y = cos 2x.
    Second, In PI the denominator should be 17. As - sign will get cancelled from numerator and denominator both.
    Let mw know if I am understanding it correct.
    Also I will suggest to pin the corrections for other students to understand better.

    I was suffering with maths in college until i found your channel
    This topic is one of the toughest topic to understand in first go. Teachers fail in making students understand this topic and so did my teacher. But honestly sir i watched your video once and understood everything. I am very grateful to you. You are the actual teacher who wants to spread knowledge and not make money.
    Thankyou so much sir for making me get my interest back in my favourite subject maths.
    And all the best, keep uploading videos we all are supporting you.
    Once again Thanks 😊😊😊
