How To Find The Exact Values of Trig Functions

This video explains how to find the exact values of trig functions such as sine, cosine, and tangent using the 30-60-90 and 45-45-90 reference triangles and using SOHCAHTOA.

You taught me in 12 minutes what my teacher couldn't in 6 weeks... from all the people learning this the night before a test, thank you!

OMG WHY THE HECK DO TEACHERS OVER COMPLICATE THINGS WHEN THIS MAN LITERALLY EXPLAINED IT IN 2 MINS!??? THANK YOU FOR SAVING MY FREAKING

[helen-fkbf]

his monotone ‘why does this keep happening’ killed me lmaoo

[lillipad]

This is the absolute best explanation of the basics of trig for people who have a visually-oriented learning style. Thank you so much.

[aaaoh]

Why don't they teach us that way at school??? Cuz it's sooo easy and understandable now! Thank you

"This computer has issues" quote from the organic chemistry teacher. 6:16 to 6:28 is my faviorte part of this video lol. Good job at explaining this concept. Most teachers make these kind of things so difficult to understand.

Good job man! Trig is interesting yet many studens are struggling with the most! Good explanation

Best Math tutor ever with a cool and calm voice 🙌🙌
You're my inspiration 😇💪

For the co-terminal angles...
The multiple of 360 closest to the number in question could be used to get the co-terminal angle a bit faster.
Who agrees with me??

This is the most helpful video on trig I’ve seen. I’m a sophomore in college taking calculus and still didn’t know how to do trig until this video.

You have single-handedly cleared all my doubts, and for that I am thankful.

Crazy how i am learning trigonometry in less than 15 minutes when my teacher spent a week teaching us and still didn’t make it easy to understand. This man is a legend. 🙏🏼

This Channel literally walked me through my entire academic path.

I studied electronics engineering and worked several years in my field, but finally decided to teach math and physics in school about 17 years ago. When started, I used this type of explanations (excepting SOHCAHTOA). Of course, they were straightforward and effective, but I was instructed by my coordinator not to do it that way because the aim is to teach math reasoning, not memorization (and SOHCAHTOA is mnemotechnic). Ever since I have been struggling with math-hater students who kind of demand the easy way of learning. Well, after explaining the math concepts and principles behind, I use this method in remedial sessions. Of course, students get it right away. Alumni who shared their experiences at university refer that what seemed to be a disadvantage at the beginning turned into an advantage because they could understand better what was going on. Don't get me wrong: the explanation is great and I found a couple of tips for my classes.

My Trig final is tomorrow and this is the one thing I had left to go over, so glad I could find this. No clue why I was never able to understand this, it's so simple seeing it this way lmao

I coincidentally have an exam about this topic today. Thank you for doing this video man.

[anotherfacelessname]

I could not figure this out for the life of me, and then I found this video and got it instantly! My teacher couldn't get through to me on this! Thank you so much! This is a life saver!

We, students, have been blessed by the gods because of your presence

This was great. I'm used to seeing triangles on the unit circle an hypotenuses of length 1. I got very confused when I saw a triangle with a hypotenuse of 2. Then I realized you just stretched everything to a factor of 2 which made me think more about it. It was great.

My teacher is good and All, but there are something's that teachers cant explain to students but only ULTRA LEGENDS can

[chepaulinus]

If you find science boring you, means you're learning from the wrong teacher, sir you're the best cause you make science super interesting, thanks very much.
