Professor Leonard is real-life superman. I've struggled with inverse functions for so long and I felt so stupid. After watching this video, I feel like I finaly understand the concept of inverse functions and it makes me feel POWERFUL!!

I now posses the power to turn non-one-to-one functions into one-to-one functions like a god. Thank you, professor! I will use my new super power wisely.

50years old and started back to college.  I found you channel and appreciate the instruction.

thank you buff dexter morgan

The toychest-to-floor analogy is super awesome. Thank you, Professor!

My nephew is a cleaning inverse.

with you always 90+   thank you sir....

Genuinely, thank you. I just passed my final exam that I had failed the semester prior. The explanations you give are so clear and concise that I had several concepts click into place all of a sudden.  I appreciate you.

Thank you, Professor Leonard this is really helpful and it gives me a clearer view and understanding of Inverse Functions. It's assisting me in reading for my BA in Computer Science.

Bro you're my fav person rn

Thank you for getting me through calculus 1 through 4 and hopefully through differential equations this January!

Thank you so much, makes a lot of sense now... U are patient and u explained down to the earth details and the why...... May u be bless with long and healthy life... Professor Leonard.

This guy said toy to toy chest, and toy chest back to floor 😂

I wish I could have found you in my 12th grade, but late here, now in college and in physics degree seeing forward to your lectures prof. Huge respect. And yes, more prosperous years ahead for you all 🌌

This dude is the man! Getting me through College Algebra! Super helpful.

Professor, your back is quite wide I couldn’t see the board properly

Thank you Prof. Leonard!
The child analogy is hilarious because it's so true!

thanks for the video I couldn't understand the inverse function til now, tomorrow I have a math exam wish me success ✨

I love your teaching style- I really understand this concept now

Just to let you know, these are still being watched! I love this stuff, thanks Leonard. This September I'm starting Theoretical Physics degree. Hope you're keeping well in your absence. 😀
