    I am a 14 year old trying to self teach myself, and I can easily understand your explanations. Your channel is criminally underrated! You deserve at least 100K imo

    Thanks for you videos.
    You dont need to Del'hospital if you factor the polynomial with the roots you found.

    Awesome content, I love the clear explanations. Keep up the good work mate, it is good to see that you are getting ads from youtube! Also, good job with your ATAR, are you pursuing mathematics at university? I am at ANU in physics!!

    Thank you so much dear *QN³*

    I have a doubt,why did you take e^iz as the primary variable in the sinx/x integral and not here?

      When you work with rational functions of trigonometric functions, it's best to make the substitution z=e^(it) since you can rewrite sin and cos in complex exponential form.

    fun fact:
    gamma(1/4)*gamma(3/4) = sqrt(2)*pi
    as well

    Dear *QN³*
    Please make a video about especial function *Ei(z)* ( actually I mean:
    Integral e^(-x)/x ).
    We can solve it with complex analysis?!
    Thank you so much
