I am currently taking 5 classes and a lab. Dynamics Electromagnetism Circuits Intro to Computer Engineering Differential Equations -Intro EE Lab I am kind of feeling overwhelmed, I just transferred to another school and I guess I kind of got overanxious and took too many classes (not used to...

Sorry if this topic has been visited in the past, but I'm having an extremely hard time with Intro to Mechanical Physics and it's a pretty awakening experience. I'm 99% certain I will fail the first test tommorrow and the reason I'm writing this rather than studying is because studying doesn't...

Hello, The last post I made included my life story, so this one will be more to the point in hopes that more will respond. I am worried I am going to fail the second quarter of mechanics (or at best get another C). I earned a 27/100 on the recent midterm. My homework scores are also below...

My class is having a debate this Monday. The debate is about "What cereal is the most nutritious" and why. So far I've been researching everything on my own. Unfortunately, when I search wikipedia or any other site that has neat little facts in it, I get distracted and go off on rabbit holes...

I am in high school chemistry and we are learning about gases. Do gases expand indefinitely? Or at least until the gas is evenly distributed throughout all the other gases that are present?

Hi, For math we were assigned a subject which we'd present during one class' hour in a group. My group got "Eigenvalues & eigenvectors". So basically first I have to give the definition and explain what it actually is (AX = \lambdaX) and then we can spend the rest of the 45 min on making class...

Should i register for one more class?? Hi all again, i had a similar thread somewhere but slightly different. I registred for classes today and i took for this spring semester: Calculus I, Elementary functions, Statistics I, Exploring the arts and sciences, and i am in a big dilema whether i...

but you decide to retake those classes to replace the failing grade. you decide you want to attend graduate school.t will graduate admission committees take only the grade that replaced the failing grade into account or will the graduate committees count both the failing grade and the grade that...

I don't mean quite what you think by that (how could I?). But I've never seen such a raw statement of the current Democratic sales pitch than today when I saw a bumper sticker on a Toyota Highlander that said "I'm too poor to vote Republican." Obviously, there are several ways to take this...

I'll have to take a class next semester as a junior level EE that I'm not really looking forward to. The reason is because of the professor. He is a nice guy to talk to, but as far as teaching, he is the worst. It is one of the most common known facts at my school. I had him for a class this...

Given the approximate values: ln(2)=0.7 and ln(10)=2.3 Use these approximations and an indirect argument using only arithmetic to explain how many decimal digits to expect in the number 2^40 and how do you know your correct? Well i know that we'll know if we are correct based on the decimal...

Just a quick question for those who have had plenty of exposure to Analysis. Currently, I'm in an Analysis class. We are using Arthur Mattuck's "Introduction to Analysis" textbook. While I think it's a good book and I enjoy the class, I can't help to think that the teacher is watering down...

QUESTION: Let L be the language with = and one binary relation symbol E. Let epsilon be the class of all L-structures A such that E interpreted by A is an equivalence relation on |A|. K = { A in epsilon | E interpreted by A has infinitley many equivalence classes }. DEFINITIONS: EC...

Is it possible to know how many equivalent class has an arbitrary group?

In my school according to my degree I require to take "Differential Equations and Linear Algebra" class but, there is another class called "Differential Equations". I am planning to transfer the next year to another school but, I don´t know which class of these two to take in order to get...

Is it worth it that I take it as a class? I'm a last year undergraduate.

All my classes are just profs doing proofs. Great. Too bad the tests requires us to use what we prove to calculate something. For example, my prof spent the first two lectures proving cross and dot product identities (the ones found on the inside covers of many math or physics books). Why...

Hi, i need help with my high school ap physics class. I'm using the college physics fifth edition book. Also are there any guides that can help me with the class with that book as the guideline. thanks
