Alright, good. I will get to work tomorrow. I still have over a month left, but I want to be one of the first people to turn it in. Again, thanks a lot. I was a bit lost in all that text.

Ay, nice man. Thanks so much. I am only in my first year of high school so I have not yet gotten into arc trig. I know sin/cos/tg etc., but Arccos is still a mystery. Will check that out. Anyway, you seem to be right. I read it all wrong. I do have a formula for the area. Unfortunately, it...

Oh damn, I did not notice your original comment. Yes, there is a diagram missing, and yes, it is meant to be solved using trig. I think it may have been meant to be 4.5 angular seconds? I will send you a link to the diagram and the whole problem here. It is in Czech though. Diagram should be...

Thanks for your response! Ah yes, that's the confusing part alright. Here's how it works: It's a set of equations, in which the input assumes that both stars are approximately the mass of Sol, because 90% of stars in the universe are within the range of 0.1 to 10 solar masses. Therefore, we...

This is the problem given at my basic astronomy course. If I turn it in within a month correctly, I get 10 extra points in the finals. Problem: We have binary star system consisting of Star A and Star B. Astronomers have observed it for 11 years, during which it has moved from point A to point...

Ah, I see. Well then, I'll give it a closer look. Thanks for the links! I'll put them to good use.

Danke! I appreciate your response. Looked over the equation, got lost pretty quick. Looks like it's way above my mathematical level, to be honest. However, I see the word "differential equation", so this is differential calculus? I'm supposed to find the method involving integration, because...

Note: I didn't really know where to put this. It isn't a specific problem, but I've been asked by my physics teacher, who decided to give me and a few others an individual physics course of sorts, to find the means of solving similar problems. It's the first problem he assigned us, since we're...

I am not much of an active member on the site, to be honest. I just come on to ask a question occasionally, get involved with the STEM community, so I would not know what generally goes on. Forgive me. Very well, I shall read more on the topic and hopefully understand better.

Precisely. It seems to me, however, that when thinking about gravity as curved space, it makes all the more sense. It helps me visualize gravitational force extremely easily. A marble in the sink, when launched with sufficient strength, will have a curved path but will escape the sink. Or, of...

I see! So gravity is both a centripetal force and a form of inertial force (though not fictitious)? Quite interesting, yet difficult to imagine. I suppose it is in general relativity that the gravitational force becomes a centripetal force and ceases to be inertial (as you stated). So in...

I see... Well, that was slightly disappointing. No need to do any mathematics now. Suppose I'll have to place my efforts elsewhere. Nonetheless, I thank you for clearing this up. I suppose this means that centrifugal force is actually nothing more than inertia at its core, or that inertia is an...

First off, I'd like to note that I am by no means a physics expert. I am merely a high school student and a physics/maths enthusiast, nothing more, so if my thoughts are completely dysfunctional and downright incorrect, which is more than a distinct possibility, please tell me. I recently took...

Thank you all for your assistance! I found it very useful! I discovered that the textbook I was using was actually meant for 4th years revising for their GCSE-type exams (it's a bit different in my country, but about equivalent in difficulty), since the exam covers just about everything from...

I certainly hope so. I wish to be educated, and I wish to pass down my knowledge when the time finally comes, and I'd hate to be broken by my mortal enemy without a proper fight. Yes, rational expressions are now my mortal enemy, as they have been ever since the beginning... I'll do my best to...
