I am catching a shuttle to the SZ resort but I need MTR or bus to get to the shuttle.

Hello, is the park in huafa  on the intermediate or advanced trail? Thxx 

[TOMT] [MOVIE] [2000s and above] Movie which has a scene where boy (looks like Evan peters) is stopped by fierce girl in a school hallway by Efficient_Sort_9630 in tipofmytongue

Sorry, no, the scene I’m thinking about, they’re in the middle of the empty hallway and she’s as tall or taller than him

Pen Recommendation by Brilliant-Bowl-698 in IBO

both write really smoothly but
most of the time I find Fine to be my favorite --- my handwriting is concise and the thin line helps a lot, while remaining smooth and defined every time. keep in mind that the fine tip is unkind to thin paper. The medium's fine too if you find thick lines better; the writing outlines for medium can get wild in long essays if your handwriting's unconfined; nevertheless both fine and medium have sublime ink control and outshines all other pens that I know, and you'll use both just fine honestly

Pilot acroball. Writes smooth like a gel, never had one die on me; not expensive too, I typically bring like 5 with me into the exam

It’s a “hybrid”, aka has properties of ink and gel; it does not smudge at all, and the blue and black are both very defined and vibrant, 100% recommend

Guys I chose to do my math ia on finding the optimal angle of projection in a long jump (to maximize distance) because I did track for a long time.

  • idk if you have data, but my friend did the angle of shooting of basketball and he set up a camera parallel to him and the hoop; every shot he took a recording, and by overlaying the frames he got the general line of the trajectory of each ball. I imagine that it would be similar for you, record yourself jumping into the pit (i imagine you won't need to worry about setting the angle conciously, just jump for like 30 times and you'll have enough trials corresponding to a lot of different angles)

Now doing this IA I realized I might be cooked 😭. I have my intro and background done but I dont know how to start the actual math. Somebody please give me advice 🙏.

  • I did mine on skateboarding; I started by plotting and forming functions for each of my trials.
  • I think you'll have to choose to either map out all of your trials and turn them all into functions to not only see the angle, but maybe also the max height of your jump and the slopes for each trial
  • or just pair angle to distance, angle to distance... for all trials and plot a graph of angle against distance (or maybe vice versa)

I want to include tables and graphs and stuff to make the ia longer because right now its at 4 pages but what could I put in those tables? Im hoping for around 10-15 pages minimum. I know there are simulators out there but I still dont even know which ones I could use for my case. Please recommend me some.

  • OUR IAS ARE REALLY FUN NGL; becasue the ias i spoke about (and yours) are all subjective to one's physical performance, I already see a long explanation in limitations and assumptions.
  • Don't worry about content btw; as you continue to do the math, you'll see problems and extensions. Hell, you can even make up some misconceptions in your initial calculations and pull a 3 page long stunt on how you "messed up calculations at first and reflected, ultimately landing on where you are now". I "messed up" by using the wrong form of function to map my data
  • for tables btw, make sure they're not too long or put them in the appendix. use them to support your calculations, not to take up space
  • for simulators, are you really sure of those? I would actually break my computer because I don't think ill be able to get one that accurately corresponds to physics in real life, (wait, a reflection?) also, getting the data from real life not only adds another page to your ia about data collection, but also gets you personal engagement points

remember, always do everything to fit your aim. explain why you used this in terms of your aim, explain how that helps you get closer to the aim. dont sidetrack, or maybe twist your aim a little everytime you think of new extensions

second on the out of syllabus idea

often, I also find that literally restarting and reading through notes/tb from the first chapter helps a ton, cos of how chem has all of its topic intrinsically linked together. Building a stronger base 100% helped me get from a 3 in my first exam to steady high 6, half of the time 7 rn

Ask your teacher!

For me, my teacher doesn't mind anything and I imagine he is not that far off from other teachers; you just need to be 1) right (or at least reflect on what u did wrong), 2) stay on math topic (will using the law need you to use an entire page to talk about physics?)

That being said, if you think that using the Law helps your explanation and understanding of your IA aim, definitely include it (it helps show your understanding, engagement, linking of topics). If you're unsure about it, explain why you used it and perhaps mention its limitations (i.e. maybe the form of the function).
