    Programs Has anyone completed degrees without more math?

    So I'm working on my bachelor's right now, junior at UC Berkeley. I've been wondering if people could share their experiences in completing their degrees without any further math (past differentials, linear, multi variable calc.). I know more math isn't required, and I've been under the...

    Electromagnetic Induction - Concentric Circles

    Just curious though, what do you mean? I'm not trying to be sarcastic (I know tone of voice and emotions don't translate well through text), but how is that not the answer to the question? Because it's asking for B (magnetic field) and that's what I solved for. And for the current, I would...

    Electromagnetic Induction - Concentric Circles

    Homework Statement A small circular metal ring of radius r is concentric with a large circular metal ring of radius 10r. Current in the outer ring flows counterclockwise due to an unpictured power supply. By adjusting the power supply, you can adjust I, the current in the large ring. The graph...

    Can Trigonometric Substitution Solve This Integral?

    I'm just tryna give insight. and yeah, i got an answer. (√2 / 2) (ln|1+x|) - (1/2) (ln|1-x|) - (1/2 - √2/2) √{ [ ( 1 + ( √x ) ] ^2 + 1} if this ain't right, there's nothing simple that can be done by hand. not all integrals have an antiderivative (for example, e^x^2)

    Can Trigonometric Substitution Solve This Integral?

    not because it's not my homework. i thought about it, i don't know why i said split it up, just straight up use partial fractions. worked for me.

    Inductance problem: mass dropped above magnetic field

    @rude man that's what we're taking right now! lol. Thanks for your help! Much appreciated =]

    Can Trigonometric Substitution Solve This Integral?

    OK, i figured it out. It's partial fraction decomposition bro. First, split up (1+x^2) as ∫ 1 / [ (1+x) (1-x) (1+x^4)^1/2] dx and do partial fraction decomposition for that. Then, do ∫ x^2 / [(1+x) (1-x) (1+x^4)^1/2] dx and do partial fractions again. Then, add the results. Let me know if...

    Can Trigonometric Substitution Solve This Integral?

    Oh shoot, I misread that... my bad.

    Can Trigonometric Substitution Solve This Integral?

    I haven't attempted to solve it, but how I would start is maybe by looking at the denominator first. 1-x^2 is a difference of squares, so write it out as (1+x)(1-x) and cancelling the top and one of the factors on the bottom. Then, the integral becomes ∫1/[(1-x)(√1+x^4)]dx Then, I would...

    Physics What is the true value of a career in physics compared to engineering?

    So do you think that I will have a problem finding a job in research? Because I read a lot that people tend to not go into physics related things even though they may have a PhD in physics. And do electrical engineers really make pretty close to what PhD physicists make?

    Physics What is the true value of a career in physics compared to engineering?

    I'm an undergrad physics major, and I constantly hear from peers and outside sources that physics majors have eight years of schooling, and get paid like dang, and that it's hard to find a job as a research physicist (that's what I want to do). I'm wondering why people say this though, because I...

    I got B = \sqrt{\frac{MgR}{(\sqrt{2gH})s^2}}
