Hi, I just recently studying special relativity in my class. It's fun and I kind of understand what's going on. But the professor skips the acceleration/deceleration part because it's for advance level. So what happens during the acceleration and deceleration (assuming the object won't get...

oh I just remember about the C. Did the 1/4 go there?

Simple Calculus question, but whaaattt?? Hi, I have a confusing math problem. So I tried to integrate \frac{x+1}{2}. Apparently I got 2 answers. answer 1. Using u substitution u=x+1, it becomes ∫\frac{1}{2}u du = \frac{u^2}{4} --> \frac{1}{4}(x+1)^{2} which becomes...

uhm because i thought engineers make good money? yea i know.. i kind of regretted it now. i'll start focusing on one thing at a time. thank you very much though. i'll look around :)

Anybody? Is there something wrong with my post? Or this is normal and I just have to wait? Thank you.

oh i forgot to say that i solved it. thank you.

What to choose: physicist, engineer, or something else?? To those who read this post, thank you first for reading this I really need help as soon as possible. Currently I'm a freshman majoring in materials engineering. I chose that major because I thought it's a combination of chemistry and...

Hi, I'm a freshman physics undergrad. I'm wondering what I can do in my four years. I have no job or research position, and I don't know if I should get one by now. I'm still in the middle of freshman physics series though. I don't even know what focus I want. Probably particle physics, but I...

Hi, I'm trying to solve this, but I keep getting both sides of the equation to be the same >.< A solid cylinder is initially moving along a flat surface without rotating. Due to the action of friction, it eventually begins rolling without slipping. The coefficient of friction is 0.22, the...

I see. Thank you all for the replies. They were really helpful. Now I just need to worry about getting the classes I need haha xD good luck to you in your study or work :)

well, in ucla, the sequence is 31A, 31B (calc single variable), 32A, 32B (both multivar calc), 33A (linear algebra), 33B (diff eq). As of PDE or ODE, I don't know anything about that :( so I can't tell. I wonder why in your school multivar is the last though.

Hahahah yea I go to ucla. I already asked some students, and none of them said it'll be too much problem. I'm asking it here to compare those courses from another school. Well, I don't know how mathematically oriented I am--32A (Calc of Several Var) is my first freshmen math class, but from my...

Hi, I'm a freshman undergrad and I want to declare major in physics. Even though the department counselor wants me to take 1 math classes at a time, the summer schedule doesn't really fit together since one math class has a time conflict with another physics class (plus I'm being stubborn). I...
