Hello there! My name is Michelle Lee and I'm an adjunct math professor at a Community College and CSU in the Bay Area of California. I've created a series of videos aimed at helping my students succeed, and I plan on expanding the range from Algebra to Calculus 3. In the future, I hope to create videos on Differential Equations and Linear Algebra. I would greatly appreciate it if you could subscribe to my channel and share it with your friends. Thank you!

@29:25 100 not -100 so it will be p^2-15p-3850=0 that is (p+55)(p-70)=0, p=-55 or p=70. Since p=70, use p-10=q hence, q=60
우리 민영이 엄청 잘하네!!!
고마워요 언니~
😮
Thank you so much!!!!
수고!!!
감사합니다 언니~
10/10 math
*Promosm* 💥
There are a lot of mistakes in the entries...So sorry for the confusion. However, all calculations are correct.
@ min 35:40, the answer is (-1 + 16 - 15) = 0 , slight error threw me off lol
So sorry about that. That was a typo...
Correction on the last problem, in L: Row3 Column1 should be 1/2 not -1/2
24:14 coefficient 2 is missing that 1+ 2x^2....+2x^7+2x^8+2x^9
열심히 가르키는 샘! 학생들이 행복하겠다!!!
You just taught me more than my professor. He has no idea how to communicate with the class.
Hi Carlile, Thank you so much for your kind words for me. Have a great day!
Nice
god bless you fr fr 😭😭
Hello professor lee
Hi. Professor Lee.
Pᵣₒmₒˢᵐ ❤️
Correction: 200 should have been added in the last step not subtracted. So sorry.
Thank you! And have a great amazing day!
Thank you so much. Have a wonderful day to you too!!!
God bless u
Thank you, Shade. God bless you too :)
God bless u
Thank you!
Thank YOU Cathie for watching this!
In last problem and very last step, there is 1/2 missing. You can see that obviously.
Hey Ms. Lee, what does the board say for when it is even at the bottom at 7:19? Thanks!
Hi Justin, that is for "Root law for limits" for all L if n is odd and for L≥0 if n is even and f(x)≥0 .
Great vid !!
great vid !!
Great vid!
Thank you so much Kelly. Have a nice summer!
Great vid!
There will be more videos after few weeks. Thank you for watching the videos.
great video !
Thank you so much
Thanks for the vid!
You are the best viewer :)
@@Michelle00725 Thank you ! I’m in your summer class and your lectures really help me understand the concepts better !
@@kellyzheng7327, I knew you are in the course before you made the comments ^^
great vid and thank you for clearing up the mistake !
I hope you don't get confused by the example.
@@Michelle00725 not at all!
thanks for the video!
22:27 (C) mistake: it should have found the limit x approaches positive infinity and negative infinity respectively. When x approaches positive infinity, the limit of the problem is positive infinity. When x approaches negative infinity, the limit of the problem is approached negative infinity. Think of the polynomial!
Thanks for the vid !
Thank YOU for the sweet comment!
great vid!
Thank you very much Kelly!
great vid !
So lovely comment always!!!
Great vid !
Thank you always, Kelly!!!
Nicely done ✅ ❤️
Thank you so much, Elena!
Great vid, it really helped me understand the material better !
I am so glad this video helps you!!!
great vid!
I really appreciate for your comment ^^
great video !
Thank you Kelly for the sweet comment :)
Great video!
Thank you so much Kelly!
Thank you so much Anthony for editing this video!
Michelle, nice lesson. Limits can be an exceedingly difficult concept to understand at first. I have one question, which isn't about Calculus. Who are the people who talk to you during the lesson?
She’s a teacher at a college, so she’s hosting a zoom meeting with her students in there!
Thank you very much John ! My students answered my questions. I told them your voice will be appeared in UA-cam and if you don't want to hear your voice in the video, you can answer in the chat instead of voice.
Thanks Michelle. You make calculus easy to understand.
Thank you so much John!
Great video Miss Lee!
Thank you Satish!
Thank you!!
