I dont know why, but i'm currently just so unmotivated and lazy in college right now.
Im going to be a junior, and I did really good during my freshmen year, pretty much getting all As or A-'s.
And then, in my sophomore year everything went to ****.
I dont have any explanation whatsoever...
Ok so for me, a job interview is still a while away, and im not even sure if i will major in CS.
But anyways, i've heard from my TAs that in their job interviews with microsoft and such, they are usually asked strange programming questions mostly involving linked lists, and riddles.
first of all, i am an aspiring EE student. At my school (as with many), students must actually apply to the engineering school usually at the end of their sophomore year. There are exceptions, such as early admission or direct freshmen admission, but most just do sophomore year.
Ok so i kind...
Ok first of all Im going to say that I am not doing EE because im afraid that ill be homeless if i just do physics.
I am genuinely interested in both.
At first I didnt know what I was going to do, but after taking physics 2 (basic EM), i knew I really wanted to go further into electronics...
is the best way to study math and science really just to do tons of practice problems?
BEcause ive always been told by my teachers, especially when preparing for standardized tests to do as many problems as possible.
Is this really the most effective way to become "good" at math and science?
This is what i dont get for things spinning in circles.
So let's say you tie a mass to the end of a string, and you start swinging the string around in a circle with a constant speed. In the absence of air resistance, then the net force on the mass would be the centripetal force provided by...
find solution using laplace transforms
y'' + 4y = 8
alright, so i did the laplace transform of both sides and i get
(s^2 + 4)L(y) - 11s - 5 = 8/s
so i isolate L(y) and i get this expression:
L(y) = (11s^2 + 5s + 8)/(s*(s^2 + 4))
however, the textbook...
A. At a particular instant, a particle of mass M = 3 kg is at the position (x,y,z) = (4,4,6) m and has velocity (2,1,-2) m/s.
B. An identical particle is placed at (x,y,z) = (-4,-4,-6) m, with velocity (-2,-1,2) m/s.
Find the angular momentum of the pair of particles about the origin...
so, list some good textbooks for undergraduate math and science.
of course early transcendentals by james steward will probably be on everyone's list for math, but let's try to get some new names.
i would say physics for scientists and engineers by serway and beichner is extremely well...
so, how analogous do u think a person about to take a test and an athlete about to compete is?
Do you guys think warming up right before a test, by doing practice problems and such, can have a dramatic effect like that of an athlete stretching before a competition?
So i was on my school's website and i noticed that the general education requirements for chemE and materials science is EXACTLY the same.
I also think i can be finished with all of the general ed requirements at the end of this year, since i got a head start with AP classes last year.
for example, a book is at rest on a table.
One might say that the normal force is the reaction force.
BUt reaction forces always have to be equal in magnitude, and you put an object on the book, then the normal force would increase to keep the book at rest, therefore the normal force is...
SO, i just had my physics midterm.
I knew how to do everything. Except these 3 problems cause me so much headache. I was so sure i was doing everything cxorrectly, but the numbers never came out that matched the choices.
those 3 problems were worth 5 points each, i ended up getting them...
so, for the very specific cases of linear systems
i can identify what shape it will be after determining the eigenvalues, but i really do not know how to go about sketching the phase planes.
can someone give me a method?
