You should be getting my tuition instead of my university. I've learned more physics, chemistry, and calculus from you these last few years than I have from most classes. Thanks!

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.
You are such a hero man. Seriously I can't think you enough, your generosity in sharing all this knowledge in such a compelling way genuinely makes me want to cry. You have helped me so much in my college classes, thank you.
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.
For Case 3, one tip my professor gave us was to solve by completing the square for the quadratic, then square rooting the function on both sides. It's a lot easier and gives you the same answer as the quadratic formula
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!
We spent an entire week on this one topic at my university and I didn't learn crap, yet after this 25 minute video I just breezed through all the homework! Thank you!
Your videos have saved me so much time especially a night before my exam. I have been watching you for years and I appreciate you for spreading the knowledge to all of us in such a simple way.
you are the reason why I am getting great grades in my engineering classes and maths can be quite difficult for me to understand. Wish you were my tutor. You are AWESOME!
Professor Organic Chemistry Tutor, thank you for an awesome video/lecture on Second Order Linear Differential Equations. Second Order Linear Differential Equations are simple to follow and understand provided that students have taken Calculus I and II. Thanks to the viewers for finding and correcting the error/errors in this video.
The legend continues...Best engineering RUclips channel there is. No matter what I am trying to learn this guy has a video for it that is guaranteed to make me understand it better than I would from class.

It was very good tutorial but i have a doubt starting from example 2 which is like y''-6y'+9=0 r^2-6y=0 not r^2-6y+9=0 (the question is given 9 not 9y but you're working the calculation as it were 9y.) make a correction sir....
Your concise 25-minute lecture was as impactful as a lengthy 4-hour session. I truly appreciate your clear explanations, Chief. Not only you cover engineering mathematics comprehensively, but you also addressed our entire semester's modules. Thank you for your invaluable contribution! 🙏❣️
Just wow, Mr. you should be really proud of what you represent for som many students. Your platform is gives so much hope to people all around the world, each one of your videos is a step closer to our goals. Thank you so very much and Merry Christmas, Professor.
College professors should learn from you because in 15 minutes you made me understand the topic and idea 10 better than sitting through 2 lectures did.
Wow😮, this is mind blowing . You were able to streamline this explanation into about 25 min 16sec . I have been looking through my materials for hours and couldn’t get any reasonable solution to the question I was pose at. Thanks 🙏 a lot sir
If there was RUclips when I studied university, I would score higher in mathematics than I did; simply because I would follow your highly instructive videos rather than attending boring lectures.
I was so confused. He made a few mistakes. To get a C, the term should have a y in it. It can't stand alone. Like for 9y''+24y'+16=0. In order to get the solution that he got, he actually solved 9y''+24y'+16y=0
Had a lecture on these today, took rigorous notes, looked at the problem sheet and came straight here 😂, i know you always got me covered bro, thank you
Just in time! Final is nearing and your first order differential helps a ton! Thanks (I haven't watch the full video but I know it's gonna rock my paper!)
Man , This guy is literally saving me for my Diff equations test tomorrow!. I'm understanding clearly with the combinations of lots of examples and a bit of theory. The professors just give you abstract theory , which doesn't help me understand on it's own!
Yeah I think he did it again in the y"+8y'+25=0 one.It has to be 25y otherwise you cannot use the e^rx when you plug it in as a solution and then come up with the ar^2+br+c=0
Hi Thank u for all vidoes in this page i'm really happy to be one of this big learning page With out u im nothing From africa sudan thank you sooooo much teacher All best wishes💗💗💗💋💋🇸🇩
in the second example, a 'y' must be attached to the '9' in the given equation to end up with a c value of 9 in the 'r' equation, no? The equation shown would be non-homogeneous.
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]

Agree! Students like us learn more from you than in university classes. We just really enrolled 'coz we don't really wanna be left out.
hahaha exactly!
just curious, what university do you attend?
Very correct
Ditto. He explains it much better than any uni tutorial.

I was thinking the same
finally someone said it .. if he do not put y all the solution should change
So is the solution in the video wrong?

0:14 when he says ''you might want to have a sheet of paper with you to take down some notes'' i felt this was gonna be hard

same I think I would have failed my first test.
Thank you so freakin much! You help me understand and learn much more than my "professors", you made me like math again :)
Your teaching style of explaining th material then immediately going into practice problems is great! Thank you!

hey bro ,(9:20) for 9y'' +24y' +16 =0 ,isn't it a none-Homogeneous equation for the constant "16 " ,or you mean "16y " instead.
Yeah I think he did it again in the y"+8y'+25=0 one.It has to be 25y otherwise you cannot use the e^rx when you plug it in as a solution and then come up with the ar^2+br+c=0
Great video tho.Helped me understand the topic.
yeah i just noticed that too
He did the same thing w the problem immediately after with y''+8y'+25 = 0
My professor basically just gace me a book and told me to figure everything out on my own... thank god for youtube
Couldn't have been a better time for posting! Thank you so much! You have helped a lot!
you are t the best tutor ever. your channel has helped me alot in my studies.
At 6:59, shouldn't this 9 be 9y? And similarly at 9:00, shouldn't the 16 be 16y?
I think so either... sir.
For the first example for case 3, how do you get the two values of Beta as 3? Why is it not + & - 3? Also thank you so much for this channel!
You explain this so much better than my professor. I love you

3rd example does this as well
it seems many of the examples do this. correct me if I'm wrong but believe this is a big mistake.
Thank you sir! Mas natututo ako sa inyo kesa sa instructor namin na puro pagawa lang alam.
Good sir, you deserve the world.
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]
Thanks a lot tutor, this is well explained way better than the lecturers in collage.
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?
Stay blessed always. Best teacher on youtube ;)
