High School What Does Δy/Δx Represent in Basic Differentiation?
I think brhmechanic answered your first 2 questions but to answer your third one: dx on it's own is called a differential. For example, for f(x) = y, dy = f'(x)*dx, and dy is the differential of y. Realize here the the differential dy is a function of f'(x) and dx, so basically one could say... -

Undergrad How to Differentiate z with Respect to ∅?
for your answer to be true, dz/d(theta) has to equal zero. differentiating: dz/d(theta)=0-(A-B)sin(2∅)+2Ccos(2∅) if dz/d∅=0, then divide by cos(2∅) on both sides and you'l get 0=-(A-B)tan(2∅)+2C solve for tan and you'll get tan(2∅)=(2C)/(A-B)- physeven

Graduate Could a star survive a direct hit from a gamma ray burst?
Will not do anything to my knowledge. It might affect the star's atmosphere infinitesimally, but don't take that word seriously. If you do the math you might get an exact value, but I believe nothing will happen to the star.- physeven

Graduate Gravitrons and General Relaivity
you have to understand the hypothesized particle first: the graviton must have a spin of 2 and be massless. to answer your question: Just what is it that the gravitron is supposedly interacting with? the graviton, as aforementioned, is a massless particle with a spin of 2. therefore it cannot...- physeven

Schools High School Plan for College Prep - Get Opinion
i highly doubt you can understand the depth of quantum mechanics without knowing the math behind it, which I'm sure that calculus AB or BC offers. However, another point of inquiry. Why are you taking physics, medicinal chemistry and quantum mechanics? seems like a rather odd combination to me...- physeven

Graduate Why is (ct)^2 negative in 4-dimensional space-time?
i don't recall the derivation in a detailed manner, but if you consider time as a fourth dimension when trying to derive the lorentz factor for time dilation using a light clock you will get -c^2t^2. I assume it works similarly for the lorentz factor for length contraction, the lorentz factor...- physeven

Electron travel in a wire; distance
you can use simple mechanics. consider the electron a point charge moving with a uniform drift velocity and i presume you will get the solution. just don't expect me to get it for you though.- physeven

Undergrad Electrons not inside the nucleus?
i think what he's trying to say is: since an unstable neutron decays into an electron and a proton, an electron and an antineutrino is, how come the decay does not occur in the nucleus, there being no electrons inside the nucleus, only protons and neutrons. This is because the electron is...- physeven

Graduate Speed of light relative to what?
Well i guess its funny now since we know better. but i can imagine myself laughing at the theory back then. I MYSELF would be the laughing stock... but fortunately i was born in a period where they are the laughing stock and not i. good point there.- physeven

well i guess what i should have said from the beginning was 'put in terms of pi/2, pi/4 and pi/6.' that would've saved us some reply notifications :P.
