The professor still looks as sharp as in the early days!!!!! I love Professor Leonard; he has taught me so much.

I absolutely love that you are still making videos. your videos saved me through two math classes when I was in college. your dedication is amazing!

I love prof. Leonard who made me love maths. ❤️

Thanks for your clear explanations, you are the best math teacher, now I really understood what I've been doing all this years. Greetings from Guatemala

Professor Leonard ,thank you for another awesome video /lecture on the Introduction to Inverse Trigonometric Functions in Precalculus/Classical Trigonometry. Transcendental functions are important functions in all levels of Mathematics and Applied Engineering.

This video should be thought of as the fundamental theorem of Trigonometry. Like if not all else understanding all the content in this video is KEY to understanding trig. Ty for this vid

I never properly got to learn this material in high school because of COVID and now that I have to use it for university calculus, it's been giving me heaps of trouble. :') But these videos are helping a lot - I feel more confident in my understanding of all the confusing trig stuff now. Thank you Prof Leonard!

Greats go Professor! Thank you for the free Tshirt!

The real hero.

Thanks prof ❤ I'm your student from Iraq

This has helped so much very much grateful to you

Many thanks for the hard job done, my son likes your channel, it is so helpful for him!

really appreciate the videos.

Amazing teacher.

great video prof

Thank you sir 🙏. This was helpful.

Tbh, I couldn't quite follow this. After watching the video that comes AFTER this (Finding Inverse Functions), where I could see it in action.. then I understood. So if you feel like it's a bit abstract here, just keep going. It gets easier to wrap your head around.

You are the best!

i love you prof leonard

what troubles me to understand is the reverse of domain and range part, you just help me to put all the pieces together, thanks for your explanation~

I am really curious about something- why can't we cut the graph of sinx at [pi/2, pi] for the inverse? similarly for other intervals and trigonometric functions as well?

I MISS U 🌸

Hi Professor Leonard, Do you do small Q&A sessions via Patreon? I am a math teacher in training in the UK and would love the opportunity to pick your brain about some teaching & classroom management strategies.

its like everything connects together, nothing in math is actually magic

Prof Leonard....❤️❤️

But (-+npi/2, -+npi/2) also works as Domain isn't it??

Me being Indian high schooler watching this video in 2x and reading subtitles to save time Also wasting time to read all the comments 😅

Prof, can you enable one-time support or donation? Thanks!

the only thing i learned during this lecture was that this man makes me feel things..

I'm from India

Lol I don’t even need to study inverse trig and I’m still here

nniou vum.fyi

Hello sir I am indian

First comment 😅👍

Ya mom

You should've given example exercises
