Our society would crumble without this man.

Very easy to understand and very helpful to me. Thank you so much!

You my sir are the man! I think ive watched every video on Trig Functions and with this Ochem final coming up on top of this has helped tremendously! Keep uploading man! Your doing a huge favor to SOO many people in the same boat as me! Much love!

honestly the only reason I'm passing college precalculus

Honestly stuck with a fill in sub right now in a college credit class and you have been saving my life. You are so freaking good at explaining not only how to do these things, but WHY you do them. Thank you.

Thank you. I wish my teacher had explained this topic as easily as this.

I'm just about done with Calc 1 and one of the last things we learned was integrals and inverse trig functions...needed a refresher, thank you for putting these out there!

I am taking trig currently and our professor teaches in a very conceptual way; this type of lecture is lifesaving so that I can understand concepts better. Thanks so much for your videos!!!

I’ve been using your videos to help me since I discovered you in geometry. I’m currently in trigonometry and will be taking pre calculus in the spring and I will continue watching your videos to help me then as well. You explain everything so well! I’m from SoCal hoping to become an aerospace engineer ,but just wanted say thank you for helping us all with your videos!

Fantastic explanation of a very confusing topic. I watched a half-dozen videos and didn't get this concept until I found your video. You made it crystal clear. Thank you so much!!

Thank you so much Brian! This definitely helped me understand and give me the upperhand on my quiz.

Thank you so much, just the video I was looking for to clear things up!

Thank you for this video! I'm taking a college-level precalculus class online and the textbook does not do a very good job of explaining these concepts.

literally had no idea how inverses work, but after watching this video, oh wow that was satisfying to learn. even 6 years later, this video never fails to educate people like me. thanks brian!

This was explained so well! I definitely understand it better now, thank you so much!

This was so helpful, thanks professor!

thank you so much I was struggling with that, then I came across your video and I finally understand

You can explain this better than my college Pre-Cal professor. You are awesome! Thank you.

Thank you sir, I wish I could had a teacher like you in my school time.

You are so helpful, thank you sooooo much!

The title is not wrong, this is a mastering lesson. Much appreciated.

Brian, you are my hero! I'm majoring in Computer Science and this is my first semester back after being out of school for 4 years! I had to drop out to work 2 jobs. So I came into this class clueless, but your videos are the only thing that is making me actually understand this material. You're incredible, man!

This was so helpful thank you Mr.McLogan!

could you make a video showing how to evaluate cosecant inverse, secant inverse, and cotangent inverse?

Huge help!! I was lost and trying to find inverse trip functions quickly so I can sleep.. exam in the am and you completely cleared it up!!! Thank you so much!

It took me literally a month to understand this concept and it all just made sense because your drawing and showing the range

This was so much help. Thanks!

I was only a minute and 7 seconds in and I went from barely knowing anything to knowing how to figure all of it out THANK YOU SO MUCH YOU TRULY ARE A MATER

if this man was a counselor... I bet his Evaluation of my parent's relationship would have stopped that that divorce

This helped so much, thank you!

Thank you so much! Saved my life before a test!

thank you sir, you explained it a lot better than my professor

the best explanation of inverse trig. functions i have found. thank you so much!

You are awesome thank you so so much!!! Been trying to understand this since trig and in AP calc now and i finally got it!!!

you are an amazing professor!!!!

man if I an algebra teacher like you I would ace the algebra sections of my tests

WOWEE Brian, you saved my life. Such a clear explanation!!!!!! THANK YOU

Sooooooo useful - thank you very much kind sir

Our society will crumble without this man

You just saved me from failing my pre-calculus midterm tomorrow. Thank you tons!

THANK YOU SO MUCH, YOU MAKE SO MUCH SENSE AND YOU HAVE REALLY SAVED ME!!!!

Super helpful, thank you very much!

Great lesson.

Really appreciate what you do thanks for the help

Thank you! This is a great review before the test! :D

I heard what you said in the last minute, man 😂. Anyways, I always admired how straightforward this video is, thanks! totally understandable, helped my ass out of this pre-calculus module.

Thank you so much!

Thank you so much for the help! Now I understand :)

Excellent! Thanks, Brian of fighting the good fight.

GREAT VIDEO!

Totally understandable video....

Im a literary crying because i dont i dont how to answer it but, when i saw this video this give some information that will help me a lot on solving these trigonometric expression. Thank you for sharing this!💙

Thank you sir for helping me 😄😊...!!

curious, but do you have a quick way to fill the unit circle out? i was thinking that putting the angles and then converting to radians.

Thank you 😊 for helping me understanding my teacher notes better ( yay 😁 now I am not confused 🤷‍♀️)

Very Helpful

Dude. I love you so much rn

Your the coolest dude I know :) thanks for all that you do

i never comment on videos but this has helped me so much! thank you!

Thank you so much! It helped me a lot

You do a good job of explaining the exact reasons for everything which is one of the harder things to convey in math to a person who isn't very math literate. I just want to say that I have watched like, 3 of your videos now and, I think its so funny that you always act surprised when you write something down wrong or 'misspeak' because you do it so often. Ur like "just gonna check something here, oh, I wrote it down wrong, HMM, that's funny" - but you must have ADD or something because you do it often. "Which one is this?...OH! I wrote down the wrong one." lol. It makes me laugh. It's actually a compliment because when teachers do that- I'm done trying to understand them. However you do a good explanation job and I can still understand you. OK, that is all. Have a good one, and thanks.

Thank you! This really help me! :))

Quick Question: At 0:16 could you put the video of you doing those functions in the info card?

Can you just come to my school and be my teacher? lol i love the way you go into dept on each problem and explain thoroughly, I really appreciate this so much. My teacher has been trying to explain this concept to me for 3 days and yet, I had no clue as to what I was doing. You, on the other hand, took less than 20 mins and i feel like i could take the final. Keep up the work Mr. McLogan!!

I’m giving another like because one just isn’t enough 👍🏼

Amazing video! I gotta prep for Calculus next year so thanks!

This guy is straight up a God. Thank you, you saved my math grade and explain things way better than my teacher

Thanks ,this really helped me

Very very ez to understand , thanks

I don't really comment, but thanks for making this video Mr.McLogan!

@Brian McLogan U are the Master !

thank you. that really helped.

this really helped..thanks

you just saved me hours of tutorials at school. thanks

i love this video!

Thanks you sir!

wow this really helped.....thank you

Thank you!

I didn't understand this at all in class, but your video helped me have my Ah Ha! moment so thank you so much!!

Thank you soooo much

Great video!

very helpful thanks master

This video really helped for my university entrance exam. Thank you sir.

Hellooo? anyone? Also when I do the reverse function of 0.707... I get a angle of 45 degrees? however when I divide Pi by 4 I get 0.7853... when reverse sin it gives me 51.75 degrees? what is up with that? why do the calculations clash and cause a roughly 6 degree difference?

Respected Sir how would you find the angle if z=1-4i

this was so much easier to understand. im gonna give it a try on my homework now. 🤟😆

Way more educational than a worldstar video, yet way less views :(

Hey guys i have a question regarding his explination. Why some inverses are not true becuae they are "outside of the range? what range exactly?

thank you man

Excellent BRAVO

Dang, he needs a new mic. Also, great video, from Floridian to Floridian!

thank you so muchh

THANK YOU!!!!! =)

What if we don't get the remarkable angles?

Hi all, can anyone help me understand this, so Brian said that pi/4 is equal to the square root of 2 divided by 2. Now when I divide pi by 4 I get an output of = (0.7853...) however when I square the root of 2 then divide it by 2 I get an output of = (0.7071...) this is of by .853, which is roughly a full unit of 1, meaning the square root of 2 divided by 2 is off by roughly 1 unit to pi/4. Is this meant to be accurate or is it ok to be off by such a small scale?

Sir please show with uncommon fractions for example 1/6, 5/7...it would be extremely helpful.. Appreciate your Teaching...No offense

This man singlehandedly taught millions of kids like me in like 5 minutes. Nice.

Hm Thanks, helped me understand this a bit more when I didn't fully get it.

for number 7, how do you know that it straight up would be pi/ 6?

I skip class my math class to watch these videos
