Ive stopped my studies because of financial shortage and now planning to go back,so I tried to find videos that will help me to refresh my brain while I don't need to pay . This is very helpful Sir. Thank you very much.

Thanks Dr. Delaware. Great lectures here.

This guy is great. I am a older non-traditional student and find his teaching method to be very helpful.

thank you so much for sharing the video of that great teacher. his explanations are owsome and precise and i hope other teachers follow the same way he did.

and by the way, for poeple who say this is not college course, i tell them that 20 years ago i mastered all what he was talking in this course, but for lack of practice during all that time i wanted to go back again to math and the that was a shock ! i forgot even things like how to add the negative numbers or the simplest fraction.

these videos are a very good reminder especially when they are done this way; preciseness, conciseness and go straight to the goal, that helps a lot. thank you doctor and the umk.

Thanks!

LEGENDARY <3

Prof! You are my hero, you and your institution are a true gift to humanity. Keep up the good work.

Ugly way of teaching ,cos of fastness

i loved this tutorial! I've been out of school for a while so it was a nice refresher.

What’s that song

Would have to pay $1800 for this at my university. Thank you

Algum brasileiro?

I am mechanical engineer since 1976 .I intrested in lectuers of Professor Richard Delaware in calculus .It is my honour to be your student ..In my primery college studies I learned calculus of the great mathmetian Tomase…

Thank you

Anyone else watching in 2018?

This might be a silly question, but is this really the level of mathematics in American colleges?

I have a question here.. since intervals are indicative of direction and order, how (- infinity, b] is possible? Because you cannot start from – infinity and go up to b. What is being shown in the diagram is more like [b, – infinity). Isn’t it?

Fantastic teacher: well spoken, consistent, patient, thorough, precise, and relatively good penmanship. This video has aged like a fine cheese.

I was trying to concentrate listening but after a minute i was like unconsciously out of mind. Aarrgh!!

"Now we could call this the denominator, but I'm gonna just call it the bottom."

I like this guy!

These sets (pun intended) of videos saved me 600 and allowed me to CLEP out of college algebra!

Currently taking college algebra. This vid was in my suggestions. Thought it was gonna blow because of how outdated it is. Watched for a half an hour because the way he teaches math is actually interesting.

What a handsome man. Really should have gotten into modelling. His considerable physical assets are wasted here.

Dear Sir : In this video i.e ( lecture 1 ) and at the time 1:05:47 ; you described both absolute values of x ( or the distance ) to be 8 units away from Zero , in fact 8 units is the distance between P & Q where these points are –3 and +5 respectively away from Zero . AM I right or I've missed something ?

Good shit…

How do I practice? Where Can I get material

was wondering if anyone could point me to a faster/less explained version of this. I catch on really quickly, so i get bored if it takes to long to explain the topic.

In india we'll be learning algebra and trigonometry at such a low level in school but no teacher explains what's going on at a basic level. This is so much more instructive and refined.

I've been trying to learn algebra for years. The last time I did it I was at uni some 10 years ago … and even then the lecturers explaining set theory and numbers explained it such a complex way that it confused me. I have all my course books still and tried to pick up from there … but they're academic and too heavy for my forgetful brain. I've tried Khans academy but its long winded going back and forth to the different topics to refresh my brain. Other youtube videos are … boring with no depth. Your course is fantastic and exactly what I've been looking. It covers everything and it's all flooding back to me. Thank you so much.

Very nice. Brookline ,Mass

Can anyone explain to me 21:31 ? I don't understand why this leads to 1. Is there anything I can look up that explains this in more detail?

Thank you (whoever you are) very much in advance.

Professor I am teacher. I was wondering if you could tell me what software and hardware you used to record this type of videos?

29:24 LOL! i had confused that in school a lot of time

It would be nice if there was a link in the description to the "logically" next video in the series. Would save a lot of time wading through the channel's videos.

Can we get questions to practice more professor?

Thanks for not having ads

one of the best math professors

Mathematics should be taught by people with personality and passion. It's too important to wasted on the lukewarm. God bless!

Thank you for revisiting me. Thank you for the lesson on 3.999 and 4.000 they're the same numbers. I'd like to join the northern university now.

Finally an explanation for the Decimal ambiguity (4=3.999…). This drove me nuts because I couldn't find out why. Thankyou Richard for the awesome lecture!

i use this to go to sleep

Perfect Professor! you get 100%
