Sorry @kinn0401 I don’t have a lot of experience with that topic. Can your teacher help give you some guidance on where to look for resources? Or you could do a search on “combinatorial optimization with video games” and see where that takes you for ideas.

You're welcome!

Happy to help

I'm glad you're finding it helpful. It was made for people just like you!

You're welcome!

My guess is that your window isn't set up properly. Make sure that you Xmin is lower than your Xmax and same with the Ymin and Ymax. Also if you are looking in the negative quadrants, make sure you are using the proper negative symbol (-) not -. Hope that helps!

Glad I could help!

You're welcome

You're welcome! All the best to you.

You're welcome!

You are absolutely right! How could I forget the very foundation when we start learning about triangles and trigonometry? Thanks for the catch!

I tend to see one almost every year. So not sure if it's the 'best' idea. But if it is something that you are interested in and you are bringing in your own thinking/approach, it is something that could be done.

You aren't able to talk about this with your teacher?

It’s been difficult since they don’t really want to offer any feedback aside from the draft. I was just curious if doing Arrows impossibility theorem was a bit too ambitious

I'm not familiar with Arrow's Impossibility Theorem and after a _very_ quick wikipedia scan, it looks like it might be too ambitious. It seems like it would be a better EE. Overall, I tend to advise students to not just pick a mathematical topic and write about it. This is why I created this video for you to go through a 'topic generation process'. I know that HL IAs might be a little more theoretical, but as I have stated many times, I haven't taught HL, so I can't speak to that directly. If you are a SL student, I would definitely advise against.

Two things... First, this is technically called an Exploration. So you don't need a research question. The main focus is (a) what are you investigating and (b) how does the _mathematics_ drive or shape your thinking? Second, there is a sample IA that is given to teachers to show students that models a basketball shot. Generally speaking, it is not advised to do the same topic that is in one of the sample IAs, unless you approach it differently. So you may want to ask your teacher about seeing that IA to see if your approach would be different and/or advisable. Good luck!

That's my goal. Check out my other non-calculator videos for content that tries to cut to the chase, but also helps you pick up on some nuances with learning math.

Hope you aced that exam!

My pleasure 😊 So glad to help!

You're welcome! So glad it helped you.

Honored

I think you should go through the process outlined in the video to help you come up with an idea. I find most people who start with a 'math concept' usually don't have much depth or interest in their IA.

Glad to help

The shapes of heavy bags are pretty simple cylinders which can be done without calculus (making something more complicated when a simple procedure is feasible doesn't make a better topic or use of mathematics). I would encourage you to look at some other object or shape.

@@LikeAMathClass what if the bags at my gym are not all the same and basic? Would this IA still be bad

You're welcome!

I'm sure you've gotten quite a bit in those two weeks. Sometimes you just need the same thing said in a different way/voice for it to click.

Awesome!

You're welcome 😊

🙏

You're welcome!

Hope it worked out for you!

Glad it was helpful.

@@tiffanymoose6397 Check your X-min and X -Max. You might need to zoom out more.

You're welcome!

Glad it helped you!

Awesome!

Learning how to use these calculators can be frustrating, but don't let it get you that worked up my friend.

You're welcome!

I'm so glad that it was helpful to you!

Np

Sounds like I've got another video to make! :) Domain: You need to look at the ends of the graph. If there are arrows, the graph continues on in that direction infinitely. If there are dots or the graph ends, then that is the end of the domain. Remember that open circles means that point is not included where closed dots means that value is also included. Range: Find the highest and lowest points on the graph. Sometimes these will be curves (called the maximum or minimum) sometimes it will be arrow (like noted in the domain). If the endpoints don't go higher than the highest/lowest point, then that is your highest/lowest value in your range. If the arrows point off past the highest/lowest point, then the range will continue on infinitely in that direction. I hope that clears things up a bit more.

To be honest, this feels waaaaay over the top for a SL Math IA. If anything, it sounds more like an EE than and IA, or more HL than SL. I would strongly recommend against this idea.

You're welcome!

I'm glad it was helpful!

As I have mentioned (in comments and I believe the video as well), I haven't taught HL. I've only taught SL Apps and SL AA. That said, the general construction of the IA is going to be the same across all four IB math courses. The big difference between SL and HL is the complexity of the mathematics. So if you feel that you really want to do a Probability IA and you have a solid idea from my other video where you are generating ideas (here's a link in case you missed that one ruclips.net/video/Fr9r6uRlbDg/видео.html), then my recommendation is to double check with your teacher to see if they agree that your level of mathematics will be appropriate for HL Apps. I hope that helps!

Hey. Well, this sounds like a lot of repeated mathematics, and the calculations/mathematics being done is a scatter plot, correlation, and possibly a trendline. Repeating the same thing over and over (4 different strokes) will knocked down with your points, _unless_ something different is happening with each stroke, which I'm guessing won't be the case. The only think I can think of, which might be difficult to do, is to try to track the motion of one of the strokes of your choice and try to model that. You can get software where you can plot points along a video and then try to model that stroke. And if you are a swimmer as well, compare that to your stroke. I get that this is getting a little further away from your original topic, but you can compare the different strokes and then look at statistics for the different strokes and see if you can see where there are issues with your stroke. But ultimately, I would not recommend you doing the same thing over and over with different strokes. I hope all this helps or gives you some more ideas. Good luck!

You're welcome!

It's possible, but it also sounds like a stretch. I prefer modeling of a a natural phenomena rather than man made structures. And with the natural, I prefer things that are in motion rather than stationary objects.
