Re: Prove me wrong

i don't think the word "indeterminate" was used here as a technical term. it was used literally, meaning that the limit can not be evaluated without knowing the specific functions and will not be the same for everything.

Re: Prove me wrong

well, as Tanvir said 1/0 simply does not exist, so there can be no question of whether you can multiply something with it or not, because there is no such thing to begin with. what i think Rafi meant by 0/0 is actually $\lim_{x \to 0} \frac{f(x)}{g(x)}$ where $\lim_{x \to 0} f(x) = \lim_{x \to 0} g(...

Re: A few questions on newtons law and black hole

the nature of the force laws depends on the mediator of the respective forces among other things. the similarity between Coulomb's law and Newton's law of gravitation is attributed to the masslessness and some other similarities between the mediators of these forces (photon for EM and graviton for g...

Re: A few questions on newtons law and black hole

just to point out, gravitational force may be fundamentally different from all the other forces. a massive object doesn't exert force on other objects, but bends the space around it so that the motion of any object passing by it is modified. and a black hole bends space so much that any straightest ...
