When I acquire my 1st engineering job, a house and a relationship, I'm sure as hell donating an arm and a leg to you because you are the reason why I'm succeeding in my college career.

"hm, i almost lost my train of thought there" A great reminder you're also human and not some super smart math android with a cool voice, haha. Thanks so much for taking the time to make these videos!

My man's going to heaven, for real💯

I know I'm late, but you are my trig savior. Watching this playlist brought my grade up 2 letter grades, and I seriously can't thank you enough

MR. Organic Chemistry Tutor, thank you for a solid introduction to Trigonometry. This is a beautiful start to old fashion mathematics.

I wish you were a teacher for computer science . You explain EVERYTHING so well in all of your videos . It's remarkable. Thank you for these videos 🙏

This helped so much. You're the reason why I'm actually getting As and loving physics even more. Thank you

Bro ,i love you,YOUR EXPLANATIONS ARE AMAZING.Just imagine to how many students did you help,you are doing crazy stuff man

You are the true example of a true real teacher Iam impressed ♥️💙💚❤😊thank you so much sir

i am going to have test tomorrow with this chapters it help me a lot best math class i have ever had (You save my GRADE)

For the basic values of theta for sin cos tan (0,30,45,60,90) you can use the trig hand trick Face your palm toward you and label your pinky (0°) and move up with the other basic values. To find sin(30°) count the number of fingers below whatever finger is labelled for 30°(ring), so there is one finger below your ring finger(pinky) For sin: Sqroot of number of fingers below/2 For cos vice versa: Sqroot of number of fingers above/2 For tan flip your hand over so your nails face you(your pinky is still 0 but it’s counting down now): Sqroot of the number of fingers above/number of fingers below 👍

I sat through the entire video on 1.5x and I have a good grasp on basic trig now... Thank you.

I don't mind if you read this or not, I've been watching you for years. I have no words to explain how much of a help you have been to me; you are the major factor for the straight grades and best math student awards I received throughout my career. You are the GREATEST math tutor I've ever had, I respect you from the bottom of my heart thank you <3

Grade 9, my teacher didnt finish this trig because of pandemic.. now im in grade 12 and taking physics and I need to go back to this.... You helped me a lot my hero. One day when i have finished my study I will support this channel by being a youtube membership... but for now I'll be just an avid learner

I start my undergraduate as an engineering freshman in about a month and a half, this man is the reason I'm here at all. Big thanks to you, Organic Chemistry Tutor 🙏 When I graduate in 4-5ish years I'll definitely have to come back to this video to drop another big thank you for helping me through my college days lmao

I want to say thank you so much, I was scared for my trig course next year but now I feel better thanks to you

I salute you, Mr. Organic Chemistry Tutor. You explained the unit circle like no one else before and you nailed it.

I'm going to take BSCE as my course. and some video said i should master trigo. And there you are my savior. Thanks alot
