Doctor Albert's Chalkboard
United States
Приєднався 12 кві 2014
Need help with math? Here at Doctor Albert's Chalkboard we provide educational videos that explain mathematics. We go through examples at the board regarding topics in Calculus and proof writing. As we continue to add content, we will provide help in even more college level mathematics.

Rings-An Introduction
We give an introduction to rings. This includes the formal definition as a set with two binary operations, different types of rings, properties of rings, direct sums, subrings and homomorphisms.

Calculus Proofs
Переглядів 1094 роки тому
We show how to prove that limits either exist or do not exist using the epsilon delta definition. Furthermore, we use the limit definition to find a derivative. For more help, visit the written post at dralb.com/2019/04/19/proving-limits/
Cardinalities
Переглядів 884 роки тому
We look at what it means for infinite sets to be the same size. In particular, we look at which sets our countably infinite or uncountably infinite. For more help, you can visit the written post at dralb.com/2018/11/28/a-number-bigger-than-infinity/
Homework: Calculus Proofs and Cardinality
Переглядів 524 роки тому
We go over homework doing proofs on limits and showing that sets have the same cardinalities. For more help in this area, visit the written post at: dralb.com/2019/04/19/proving-limits/ dralb.com/2018/11/28/a-number-bigger-than-infinity/
Homomorphisms
Переглядів 764 роки тому
We define group homomorphisms and the kernel thereof. Then, we show the fundamental theorem of homomorphisms for groups, that is, that there is a one-to-one relationship between homomorphisms and normal subgroups.

Homework-Mappings
Переглядів 454 роки тому
We work through the homework on mappings. In particular, we work with examples showing that a given relation is a mapping, is one-to-one and onto.
Chapter 11 and 12 Homework
Переглядів 1054 роки тому
We go over homework giving proofs involving sets and non-conditional statements.
MATH 300-4/13-Mappings Part 2
Переглядів 384 роки тому
We continue to look how proving that mappings are one-to-one and onto. For more help, visit the written post at dralb.com/2019/04/19/bijective-mappings/
MATH 211-4/9-Set Proofs
Переглядів 1924 роки тому
We show how to prove that something is or isn't an element of a set. Then, we work on proofs involving subsets. Finally, we show how to prove that two sets are equal. For more help, visit the written posts at dralb.com/2019/03/31/set-equality-proof/

bro thanks alot
thank you king, needed this
Best 6 minutes ever. I've been trying to understand for an hour.
This is the clearest explanation i found so far. Thank you very much!!
Thanks. Finally I understood Kernel topic
Distributive law?
Amazing dude
Bro you just saved my life.
very good and simple video
The lectures are so marvellous! and the channel is so underrated.. Wishing you lots of health and happiness to your family, Professor.!
Fuck😅
❤❤
Amazing explaination sir thanks alot👌🏻👏🏻🙂🙏🏻

this helped a lot. awesome work explaining it simply in all in one video.
well done.
Thanks. Great video.
Very well made video, really helped in my discrete math class.
Thx
Thank you
From indian🙏
How do I select a suitable centre point for any taylor series
thank you sir
This is the best and most concise video I have found on this topic. Thank you so much!
you my hero....nice method🤍
Thanks a lot sir
We'll done!
The video was really helpful
You are a diamond in the rough. Great lecturer
I actually understood what you said.. Thanks for making this video..
You are welcome, I’m glad you understood it.
Ty for the help!
You are welcome, I’m glad you found the video helpful.
It's so cute how he keeps dropping the pens.
Thank you! This was explained very well!
I appreciate the feedback and I’m glad you thought so.
The thought process at the beginning was especially helpful
Thank you for letting me know, I’m glad it helped.
Thank you for making these videos. They have been extremely helpful.
Could you explain why you chose k=2 as your starting value when checking for absolute/conditional convergence?
If you use k=0 or k=1, the terms are undefined because you get 1/0 or -1/0. Therefore the series would be undefined. Hence, as part of the problem, it needs to be stated that we start at 2 or later for the series. Since the series starts at 2, the integral should also start at 2.
STEM and leaf That makes perfect sense. Thanks for the speedy reply!
