Introduction to Logarithms and Their Graphs (Precalculus - College Algebra 55)

A study of logarithms from the vantage point of being the inverse of an exponential. Focus will be on the creation of the graph of the logarithm and how to change between logarithmic and exponential notation.

The world needs more people like professor leonard. I don't have words to express my gratitude. he explains step by step without overlooking anything. He really knows the mind of a student and explains each and every detail perfectly. Thank you very much.

Every time I watch one of your videos, There is this ad that pops up saying

"STILL SEARCHING FOR MATHS HELP ON YOUTUBE? ARE THE VIDEOS FROM 2006 REALLY HELPING?"


ME: *Laughs in Professor Leonard* 🤭

[Saygoodbye]

The best teacher. I have so much fun doing math. I always loved math. And you keep it straight forward and fun! Thank you professor.

21:01 you were looking so cute over that smile. May you live a long long life that even my kids watch you and say I topped because of PROF. LEONARD.

I was waiting for this for very long and finally get this.
Thanks Professor

Not only have you taught me math, you made me smile about dramatic calculators in a world right now where it is hard to laugh. You're the best!

[TrailblazerNurow]

I'm so grateful for all his lectures so amazing

[naradakandawala]

Best professor ever who knows the path to be a real professor❤

[btaylor]

You wouldn't believe how perfect the timing of this video is. I can't wait for the logarithm/exponential properties video!

Hey everyone, it’s finals week, let’s go prof Leonard!

[jeremiahfourtwenty]

Love these aha moments thank you professor Leonard

The domain of a logarithm is essentially a combination of the domain of a radical function (even index only), where the radicand cannot be *negative*, and the domain of a rational function, where the denominator cannot be *0* . The domain of a logarithm says the argument cannot be *negative* or *0* .

Professor, you are awesome, love your lectures!!

At roughly 41:00 in. That right there. If that could have been explained that way in all classrooms I don’t think students would have such bad problems with Logarithms.
18 years ago in my last math class with Logarithms, we were told “It’s the inverse of an exponent, figure it out” and two thirds of the class failed that section. I wish I had YouTube back when haha.

I'd love to see a video of how to change the order of integration with a given triple integral. Love your videos and blessed that you exist. I'd be failing calc 3 without you.

thanks a lot for all the top quality content you put on your channel sir, i, as student who graduated with a master degree in cs, always felt intimidated by math specially calculus because i was never taught to think about math but only to memorize it. thanks to you im relearning now . thanks a lot !

[luwaarosina]

Really appreciated this video professor, I got them today and they are all useful on log and exponential.

Can professor please make a video on limits and continuity ( left & right limits , improper limits, and continuity in terms of limits) please .
Thanks 🙏🙏

Logarithms are my Bae <3 ... BAE: Base, Answer, Exponent .... log of base (answer) = exponent

[georgesadler]

Professor Leonard, thank you for another monster, Introduction to Logarithms and Their Graphs. Logarithms and Exponentials are common in math, science and engineering. Scientist use logarithms to study earthquakes on planet earth.

Whew, your vids have helped me this few years in college & now I am finished! 🤘🏾No math in law school I hope! 😩 Thank you. 💜
