The name trinomial refers to three non-zero terms(at least that's how I treat it), which is the key difference between the two definitions you offer. P(x) is a trinomial because, by definition, it has three non-zero terms. I don't think I've seen anyone refer to something based on its max number...

From my understanding, the definition of a "term" in a polynomial refers to the individual pieces (non-zero) separated by addition or subtraction notation. So in the above example, I would consider it having 3 terms. A monomial doesn't mean it has to be degree one; 5x^2 is also a monomial, for...

TL;DR Summary: Making a model helicopter for SCIOLY I have a national tournament for Science Olympiad, and for one of my events (topics), my partner and I are essentially starting over. The event name is Helicopter, and requires students to make a model "Helicopter," although it doesn't look...

Yes I found a online copy for much cheaper, I might see if I can find a preview of the book for free just so I can see if I should get a physical copy. Appreciate the advice thanks.

Anybodys whos read the book Second year of Calculus, from celestial mechanics to Special relativity, what are your thoughts on it? Would you recommend it? What faults does it have? Any information about the book would be helpful.

This helps a lot thanks

Thanks so much, I'll definitely try doing a practice test or two to see what I need to work on

TL;DR Summary: How should I study for the F=ma competition as a total newby to competition physics? Hi, next year I'm hoping to do the F=ma physics competition. I wanted to start preparing beforehand so Im not too panicked a day before the competition. Does anybody with experience in this...

Thanks this was really informative

I was reading about how Sirius A and B were part of a binary star system, im familiar with the concept of binary star systems and even a little bit of how they discovered, as well as spectroscopic and eclipsing binary star systems. However, I still dont know how to calculate period or just...

This was great, thanks!

Yes that helps a lot, the previous website I was looking at wasn't the easiest to understand. Thank you

I just looked a little bit into how Nuclear power plants work out of curiosity, and I saw that the Uranium they use is U-235, but when I was looking at a website, it said that the Uranium required 3% or higher content of U-235. I wasn't sure if this was correct so I dug a bit deeper at the...

For higher-level math, specifically Geometry, people say that Euclidean Geometry in Math Olympiads by Evan Chen is pretty good. I read my friend's copy a bit, and I have to say the first two chapters were good, but it's important not to skip around, cause it's really easy to miss a key detail.

Thank you so much
