It’s amazing how this dude can take something my professor makes so complicated and make it extremely clear

[ryzurrin]

I think I would fail at life without these videos my friend, you are simply the best there is at explaining complex subjects in such a way that things become clear and understandable. I wish I could download your brain into my brain and just simply have all this wisdom. But I suppose that is what we are doing in a sense by watching all your videos!

[antonettgreen]

I have teach this tomorrow in a presentation....its the first I am doing this topic....your explanations are clear and concise . Thank you

[jgf]

I've left a similar comment on hundreds of your videos but, again, a thousand times thank you for these! I'd be drowning without these videos

[-exe]

these videos are the reason why i'm still passing my classes thank you so much!

[oniccarm]

I was having challenges with this but now I'm not. Thank yooouuuu so much. I'm writing a quizz tomorrow about this chapter, so thank you for your efforts. We highly appreciate you 🤝

It's amazing how i first started watching this guy in year 3 and that I still am despite being in my first year of university now. wild

I have a calc 3 exam in 6 days and need to learn almost everything from the ground up. Im in the right place. Thank you!!

when i learned this in Santa Barbara calif in 1974, my teacher Traughburg used to call the <a, b, c> 'direction numbers' and i understood it so well as a 20 yr old...now i am 69

Professor Organic Chemistry Tutor, thank you for a well explained video/lecture on Vector, Symmetric and Parametric Equations of a line in 3D coordinate system in Calculus Three. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

[angelbwalya]

I think we should be paying our tuition fees to this man.. he's really a genius

[alexanderquilty]

You are the best organic chem tutor! However my final is next week lmao but! It will make for good review! Thank you !

[m.muhammadsodiq]

Bro you are so I love your lessons. You clearly explained my professors boring lecture. I always recommend your lessons to friend. Go on bro. Good luck on your job. By the way, thanks so much for awesome lessons.

[weijietang]

You are the best math teacher I ever meet.

[yryskeldianarbekov]

Braah, what??? You teach everything I have to learn. Haha

[christiandelgado]

I love all your helpful videos. You make them very simple but teach what is needed. It really takes stress off of learning this chapter.

[tsungichisungwa]

I have an exam next week and after seeing this video I’m definitely going to get A+

[teddybear]

I have a test on this tomorrow! Thanks!
