Trig review basic graphs 9 10 21
Переглядів 1703 роки тому
In this video, we review the graphs of the 6 trig functions. This video covers just the basic graphs (no transformations) with an emphasis on understanding over just memorization.

Practice using the sum formula for tangent given various bits of information about the two angles in the sum. I make a careless mistake early on, miscopying a 7 as a 2. Current students: there is a handout posted on Canvas that shows how to simplify the correct expression. I point out the error on the screen; you can choose to either just read through the handout or watch the remaining part of ...

I have check at least four calculus books but no explanation is as satisfactory as yours. Thanks professor.
You one of the best teachers i ever came accross on youtube you have to improve your camera quality please
Thank you for articulating every step, making me think and understand. 🙂🙃🙂
Hmm, I think I know what I'm looking at. I think you just up'd my game. How come your spirals don't hit the center then veer off to the right with a squiggle? Sorry, bad terminology. I'm not in your class. I'm just a loser bum, not a mathematician. I took a linear algebra class and dropped out. I think we are in the same ballpark though, but our functions are a bit different. So, the quadratics are two axes of rotations. They can make a sink or a 3d wave. Cubic's have three axes of rotations. So on and so forth. I imagine these all make Rhume Lines when projected onto spheres.
4:32 I think the denominator should be r^2(r^2cos^4theta + sin^2theta)
May you do nullclines for the SIR model which includes alpha and gamma?
thank you so much
Very good explanation.Thank you
Could u suggest a calculus book with many δε, Ν & Μ Limit proof examples, and explanation like u explain?
U should author a book on Calculus with many examples of ε δ limit proofs, u explained it so well. U are blessed with a brilliant mind. U left no doubt in my mind about even the smallest things. For the first time my mind is accepting with clarity every aspect in the solution around ε δ proof from the beginning to the end. Thank you so much
Awesome professor, Educator Could u do few more examples using rational functions, quadratic, cubics, radicals?
what if the limit is not true, what happens then
Nice
magnificent teacher!
Thank you for this great explanation!
phenomenal explanation! Thank you
This is really great! Thank you!
Hello, could you give me a download link to use this software? I need it badly but I can't find anywhere where I can download it. Thanks
Thank you thank you
Waaw
Want if i choose delta Lessthan or equal to 2. Is it correct
thanks0000000000000thanks

Thank you so much!
Great work, you are an amazing professor, the way breakdown concepts an explain is probably one of the best I have seen and you passion for teaching is evident. I thank you and support your endeavor to make a significant impact in the minds of curios and hungry to learn from a real master. 👌🏾
Thanks 👍👍
Help with the name wana search for more of your videos,your amazing
What I think is kind of sketchy about these epsilon - delta proofs is the need to 'pre-suppose' what we are trying to prove in order to find a value or set of values for the variable 'delta'. It REALLY seems like some-sort of circular logic. Pre-supposing that 'idea', for lack of a better term, then demonstrating it works in the other direction (essentially just substituting it back into the proof, just 'undoing' all the algebra we did to find it), just seems like circular - logic. We learn these proofs in calculus one, see them maybe on the corresponding midterms / the final exam, and BAM never seen again. These proofs are just a logic fallacy, and a waste of time and brain power.
delta must be min{1, ...}. etc. your explain delta <=1 is not correct.
I have found salvation! Thank you!
Great explanation...thx
Thank you indeed
You're amazing. I am working on an equation for fun, could I pick your brain? I can send me email/phone if you can help me 😊
This teacher is just amazing. i dont know why it is that she doesnt have a lot of subscribers
Excellent! Thank you
Anyone know why we have to bound delta to be less than one, why not some other number.
We often use 1 because it makes the math easy, but you can choose any positive number like 1, pi, 1/e, 52!, etc.
@@ScytheCurie52! 😂
@@ScytheCuriethe whole essence of limits is to come closer as possible therefore 2+ delta is good estimate. Also remember that the goal of the proof is to determine that the limit exists at x = 2 and that it is actually 4. So delta must be close enough to 2
Amazing. What an amazing explanation. Thank you very much, professor.
Thank you so, so, so much for this video. I was having some problems trying to understand the directions thing and here you explained all clearly. Suddenly while watching my mind was just like "wooooow, now I see!!" Thank you ^^
Thanks
This was the most challenging thing that I've seen thus far in my review of mathematics.
thank you
Thank you!
When I first watched this video I didn't understand.on the next day i watched it again.now I'm teaching my fellow students the same solutions.what I thought was complicated is now very easy.thankyou so much for the deep explanation.you earned my respect❤️✍🏾🙂
john, I agree with you. The final answer should be ( root91)/7?
Thanks very much...that was very helpful
Bien expliqué ..Bravo Karla et MERCI
"I'm not stopping just because I'm tired... I'm stopping because I'm done." Lol, very helpful, in fact so much more helpful than my textbook. I'm still confused, but I feel I'm a lot closer after this video.
Thank you for these lectures. You calculus lectures have helped me a lot!
thank you!
Thank you so much for these videos I'm doing this course and my professor sucks
