When analyzing the transient development of a circuit containing a DC voltage source, capacitor and resistor in parallel, how might one explain the fact that 1. the voltage drop across the resistor changes with that of the capacitor. 2. The first loop containing the capacitor and DC source seem...

can the problem not be split up in some way as to mathematically describe the changes in momentum like the ballistic pendulum for example..

what does that mean, momentum is not conserved?? is it not a law that it always is..?

ok, new scenario, describe the momentum changes when the impacted object is stationary by all means (maybe it's even mounted) and is impacted by a high velocity object and the collision is completely inelastic

if a nice fuzzy block is stationary on a frictionless surface and is hit by a high velocity bullet in such a way that the bullet cleanly penetrates and exits the box leaving the box stationary but the velocity of the bullet slightly changed, what can one say about the conservation of momentum of...

thank you :) I don't know why it seems so obvious now ..I did think of the t as being a result of the chain rule but for some reason the way they wrote it down made no sense to me and had me stuck...I think it's because they wrote (∂ƒ(tx1,tx2,…,txn)/∂x1) which to me means with respect to x(...

I've been reading a book on economics and they defined a homogeneous function as: ƒ(x1,x2,…,xn) such that ƒ(tx1,tx2,…,txn)=tkƒ(x1,x2,…,xn) ..totally understandable.. they further explained that a direct result from this is that the partial derivative of such a function will be homogeneous to the...

Im sorry I am still coming to terms with the fact that philosophy (or some degree of it at least) is not allowed in a physics forum, i find the lines between the two a bit blurred and unconsciously most of the time i find myself leaning toward the philosophical side of physics..i feel that's...

Ok, can i rephrase that.. From "the beauty" to "the functionality (with respect to nature and the human sense experience ) and the mathematical significance of its discovery...

As a mathematician, what may you say are the beauties that you see in the Mandelbrot set??

Im sorry to be off topic but I'm using a i device and i can't see (what i think to be) mathematical symbols that are in this thread... They appear as dollar signs and other randoms, i was wondering if maybe I'm short of additional download or setting adjustments. All help is highly appreciated
