Math Made Easy with Tammy Barker
США
Добавлен 20 окт 2016
Hi everyone. Welcome to my math RUclips Channel. Here you'll find short lectures and tutorials for many math subjects. I have many videos organized into playlists to help guide you to videos with common objectives. I try to keep videos short, so that they are not overwhelming. Often videos build, so watching them in the playlist order can help you learn in manageable steps. I also have videos for using technology in mathematics including Desmos (my favorite), the TI-84 graphing calculator and Excel. I hope the videos are helpful! Best wishes as you learn the beauty of mathematics.
Conditional Probability and Independent Events
This video explains how to find the probability that an event A will occur when you know that an event B has already occurred. I'll cover notation and examples then tie in the concept of independent events.

This works for any person you want to use in the equation but you start with the older person's age. No matter who, all of humanity is your soul mate.
Great video, however i don't know if it's due to Demos graph has been updated or not, it won't show the left tab of the desmos graph calculator, they will have do open in a different window. I tried adjusting the width and height of the code but didn't work unfortunately. If will still show the graph, just not the function tab on the left.
Try this video. ruclips.net/video/9CQm0oRO584/видео.htmlsi=oayABXZZqVxRQa0k it has additional code. I think putting the width at 100% might be better than putting in a number.
What if 19 born 04
Thank you for this! I knew it had to be a reverse math equation because I started trying different peoples ages with mine and they all were my ‘soulmate’ 😂

Very useful, thank you very much!
Excellent video. Thank you
Hi do you know what type of math is 116
I think that would depend on the numbering system at the college or university you are attending. I taught Math 116 in Nevada, where the course is technical math.
@tammybarker1226 yes I'm in Las Vegas I'm going to csn
@tammybarker1226 what math should I study to prepare myself
Suggestion, the calculator defines payments as cash inflows (+) and cash outflows (-). Since your initial payment of 5,000 is a cash outflow (from your personal standpoint), plug it in as a negative number.
Thank you, so the augmented matrix is just a regular matrix, I expected there is a specific symbol in geogebra for augmented matrix
Thank you

Thank you! What's your LinkedIn account link?

W, nice video

Thank you! Exactly what I needed, explained well.

Thankyou!🤍
The example at minute 5:26 with hockey players can be represented as "all canadians are men" ...so isn't it invalid?
I think you are referring to when I said you can make the circle small inside. What I meant there is that the circle for Canadians could be small and stay inside of the circle that is labeled M or it can be drawn bigger (the way I drew it) to go outside of the 2 circles in the Venn Diagram. Any way you draw the circle for Canadians it will touch the M circle. If we drew it in a way that all Canadians are men the argument will be valid even if the overall argument is not true. That's part of the confusing part with logic, we don't want to confuse truth and validity.

The code doesn’t work.
I double checked this time. This will work: <p>< src="www.desmos.com/calculator" width="1000" height="800"></></p>

Where did you share the code you pasted into the embed?
Here's the code: < src="www.desmos.com/calculator/h6sgz16d4j?embed" width="500" height="500" style="border: 1px solid #ccc" frameborder=0></> I'lll put in in the description for the video as well.

Professor Barker I got a C+ in my math class thanks to your RUclips channel and Professor Osama. Thank you for everything you do.
So glad you continue to do well in your courses :)
Hi, Can we derive this equation from graphing on Desmos ?
I didn't know this was possible, thanks it worked!
Thank you so much for everything you do for your students. You are the best professor ever. I hope to have you in my other math classes.
Keep doing what you’re doing, you have helped approximately 76 thousand viewers and that can only increase!! You’re amazing 🤝
you rock!!!! hats of to you for creating educational content, i could not string enough words together to adequately describe how spectacularly appreciative i am of your contributions to the maths community
Off topic but I've noticed there is lag when writing (user input) and the output being displayed on the screen. Is there a way to minimize lag and make it non existent. What hardware would i need to make this happen? I've seen folks off youtube able to free flow with zero lag who are unwilling to share their secrets. Could you kindly shed light on how they're able to accomplish this? Thanks.
thank you very much
This has helped me so much, you explain everything very clear! Thank you
prof tammy, pls take over for my professor <3
I tried it with different numbers it all come out the same so it’s just something fun to do

Uh, doesn't your last diagram say that every U.S. citizen is in the Army?
So here's the interesting thing with Euler diagrams, you have to not in part your knowledge into the drawing. We may know that some U.S. citizens are not in the Army, and we could have drawn the diagram to show that, but nothing from the premise gave us that information. When we draw the diagram we just want to make sure the diagram shows that the premise are true and then we try to tell if we can therefore conclude that the conclusion is also true. Try this: Do the problem as this argument All Beagles are mammals. All Beagles are dogs. Therefore all mammals are dogs. It's a similar argument in structure but because we know all dogs are mammals you probably wouldn't draw the dog circle outside of the mammal circle. Euler Diagrams sometimes require you to turn off knowledge that is not in the argument so that you can stick to what is given. This shows you how logic is so important to fields like law. Only argue what you can prove. Hope that helps.
@@tammybarker1226 Thanks, but it's VERY nonintuitive.

Thank you it is so informative!
These clips are very useful for students of schools.
Glad you think so!
Great job!
very good video, helped out a lot!
Glad to hear it!
This didn't work for us. Does that mean we are true soulmates???
No, maybe it means one of you had a birthday this year and the other person has not, that would explain the difference in the answer.

Thank you queen Tammy. You really popped off with this video!!
I appreciate that
Very nice!
Thank you! Cheers!
FYI - at 4:38 that is a picture of Bernhard Riemann, not Christian Goldbach. Also all prime numbers are either one more, or one less than multiples of 6 to my knowledge.
Oh no. I didn't mean to have the wrong picture. The one more or less than multiples of 6 would not work for the prime numbers 2 and 3, but otherwise that's a great addition to the information :) Thanks

Perhaps the Twin Prime Conjecture can be proven from inference based on the twin prime counts in the matrices of the “Architecture of the Primes” (see bigprimenumber.com). The matrices are bounded by prime factorials (PF) 6, 30, 210, 2310, 30030, 510510 etc. Matrix 2 is between 6 and 30 and has 2 twin pairs (11/13, 17/19). In Matrix 3, bounded by 30 and 210, we find 10 new twin pairs (41/43, 59/61, 71,73, 101/103, 107/109, 137/139, 149/151, 179/181, 191/193, 197/199). Note that each number is derived by adding a multiple of the lower bound prime factorial 30 to one of the prime numbers (with some exceptions for relatively prime numbers) so 41 + 30 = 71, 11+3*30 = 101, …19+4*30=139 etc. Matrix 4, bounded by 210 and 2310, has 39 additional twin pairs. There are an infinite number of matrices. As the density of twin pairs per matrix is increasing, the number of twin pairs is therefore infinite.
