in video at the point 1:19:07 i think you solved it wrong y should be less or equal to x/3+3
Thanks for pointing that out. I made a mistake. Seems I cannot edit it here. So I just deleted that question. Many thanks.
@@wangtianjiao no need to thank me sir your videos are amazing.
i just wanted to clarify my doubt.
@@rsreenivas1880 No problem. Thanks for your support.
@@wangtianjiao sir what software do you use for teaching?
do all the chapters on all the aops books
Stay tuned :-)
Can you please post the lessons for other chapters. Please, thanks 😊
I am trying to my best. I have other work to do so it could take a while to complete this whole course. Stay tuned. Many thanks for your support.
@@wangtianjiao thank you
I have been watching you since day 1
Assalamualaikum, if u kindly could provide me the pdf of aops introduction to algebra solutions manual i would be really greateful for ur help. Anyway appreciate ur work, please keep it up.
Many thanks for your support. Sorry I do not own that manual.
@@wangtianjiao in that case, i humbly request u to explain the solutions of all exercises and different problem solving strategies of that book. Anyway, thanks for ur reply, hope i didnt waste ur time(i really love mathematics😂).
@@nizamkanchon3311 OK keep tuned. I ll help as much as I can.
hey , provide some dsat math topics
Maybe in the future. Currently I am doing the AoPS topics
How would you recommened the AOPS introduction to algebra book on a scale of 10? I’ve been thinking of buying one for myself, is it worth it? I have a bit of algebra background since im still currently in highschool, but haven’t really gone in depth in said subject.
Please try the official diagnostic tests for intro to algebra A here at: data.artofproblemsolving.com/course-docs/diagnostics/algebra-a-posttest.pdf and then intro to algebra B here at: data.artofproblemsolving.com/course-docs/diagnostics/algebra-b-posttest.pdf If you can solve nearly all of the problems there with little difficulty, then you could probably move on to the next level.
@@wangtianjiao thank you very much! this helped me a ton, earned subbed
@@dangodono6096 No problem. I ll help as much as I can 🙂
Thank you very much, very helpful for my son’s learning ❤
@@tinaguo2156 Many thanks for your support :-)
Thanks for the videos, I appreciate you putting out courses like this
Many thanks for your support. 🙂
ohio is so skibidi
hello, why is this not following the order of aops?
Hi. It is following the order of AoPS. Topic 1 here covers the Chapter 1 and Chapter 2 in the textbook. - Sometimes I just consolidate more than 1 chapters of the textbook into one topic in my video.
Thanks for hearing my suggestion Dr. Tianjiao Wang it really helps me
No problem. I will help as much as I can.
Thank you for the video. Do you have any plans to run a course based on the Intermediate Algebra book?
Yes. When I have the time I ll do it in the future.
Are you also going to cover the intro to number theory?
Yes, I will do this later in the future.
老师讲的好好，订阅了😍
Many thanks. Are you Cao C. Y. ???
Hey Dr. Tianjiao can you atleast go at the chpt 1 so i can understand better
Do you mean go over all the contents in Chapter 1?
@@wangtianjiao Yes sir
I'm actually reading Introduction to Algebra but, i can't get all the knowledge in the book. And i want to join our National Team in my country for the IPho which is a dream, so am doing the foundations now.
Glad to hear that. Wish you all the best!!! I will upload contents at times when I am free. Currently too busy to update >_<@@saikikusou20
@@wangtianjiao Thank you Dr Wang
才看到这个视频，本来还想买书呢，这下这钱省了🎉，多谢!❤
Correction: @37:07-48:29, the angle made by the rope and the direction of motion should be 68 degrees, not 22 degrees.
thank you
Where can I get OSSD all subjects pdf download please
i wanna only exercises answers. plz send me exercise answers not solution

Or you could just do something else
It'a interesting how you do so much work to have 139subs bro
bruh dis is 2 years old
wow first comment
Thank you very much, I appreciate what you do keep it up!
Thank you very much for your support!
物理好难😭，但是很有趣。
Sorry, audio was not recorded properly. . . ;-(, will update when I have the time ...
Thank you for these continued videos
Glad you like them!
1:19:52 in Sample Problem 2, well, if the spring-mass system is vertical, "as it compresses 0.19 m" should be "as it compresses 0.19 m with respect to the equilibrium position", to avoid confusion.
Correction: at 51:30, in the FBD, the static friction excerted on m1 should be pointing to the up right in parallel with the ramp, not down left.
Good content
Very nice Dr. Wang!
Thank you very much !!!
The whole class has clear ideas, compact links, prominent key and difficult points, and reasonable design. The teacher also provides rich content and gives students sufficient opportunities to explore independently in the whole teaching process, so that students can learn and improve themselves in the activities.
Many thanks !
Sorry, I have recorded the lecturer's screen but not the audience screen by mistake ... will fix this later
很详细
Thanks. Glad that it helps.
Errata: 00:00-00:03, Course Title should be MHF4U, not MDM4U
16:26 1 and 3 ?
Yes, that should be {1, 3}. Sorry for the typo.

These videos are extremely useful, may I know it is presented by youself?
Many thanks. Yes. But I did not have time to edit them. They were recorded while I was teaching my niece :-)
