      I'm kinda jealous. My teacher covered this and more in one 1h15min lecture. I wish we were able to go at slower pace, but that would only be possible if the university added a lecture period every week, which they won't do :(

    I appreciate how you dive quickly into actually solving problems, rather than getting bogged down in theory. At times the theory is important, but most of the time we just need to get straight down to business. In the long run, this no-nonsense format is more useful than any other math tutor on youtube.

    I'm here right now because I wanted to thank you personally, Mr. Organic chemistry tutor. The clarity of your videos, with your heartfelt yet joyful tone, brings tears to my eyes. I am but a mortal vessel, and as such, I am unable to adequately articulate the sense of divinity and celestial dominance your video explanations have bestowed upon me. The whim and astonishment that each soul touching connection left is enough to stimulate the previously sluggish flow of deep emotions that have lied in the depths of my soul after my university lectures. Thank you very much, Mr. Organic chemistry tutor for your beautiful explnantions.

    I love that these videos always explain each step, even stuff learned in previous math classes. I'm doing this in calc 2 right now, but I always get rusty on factoring polynomials when I haven't done it in a while, but whenever he explains it I feel like it all comes back. My professor would probably just say that we learned this in Int. Algebra which is true but we can't always remember everything off the top of our heads!

    This 25 minute video sums up all the stuffs in my 19-page module, I can't understand a thing in it until I watched this video.

    9:07 the equation for the question should be 9[(d^2)y]/[d(x^2)] + 24 dy/dx + 16y = 0 instead of 9[(d^2)y]/[d(x^2)] + 24 dy/dx + 16 = 0 [we are missing the `y` for 16y]. the final answer is correct though.
    Same thing for the equation for the question at 13:00 should be y'' + 8y' + 25y = 0 instead of y'' + 8y' + 25 = 0 [we are missing the y variable at the end]

    On the second example, did he forget to put y on 9 or you can still use quadratic equation even if 9 is only 9 and not 9y?
