Hi Redbelly98, yes I do know how to find the slope and all but I need help with the syntax with which to write a code so that Mathematica and do it. Now for example, if I use NSolve to solve for a slope at a particular place, it gives me for example x-> 0.2. Does anyone know how I can use...

Hello everyone, I am working on trying to model a bouncing light ray between two curves, and I would like to model it in Mathematica. However, I do not know what syntax or how to go about typing the code in. I tried to find examples on the Mathematica Documentation Centre but the examples...

Hi, I did know that the angular velocities for each cylinders are different v=R\omega_{M}=r\omega_{m} , thus \omega_{m}=\frac{\dot{x}}{rR}R=\frac{\dot{x}}{r} Which I have taken into account already in the last term which is the small cylinder's own rotational kinetic energy about its...

Hi everyone, not a homework problem, just something I was thinking about when I found in a book. Homework Statement A hollow Cylinder is rolling down an incline of angle theta. Inside the cylinder is a smaller solid cylinder rolling freely inside it. (Refer to diagram) Given an x...

Thanks Doc Al. I must have confused myself! :) Problem solved.

Apologies for bringing this up after so long. I too was looking at a similar problem to Saulius and I merely want to find the total stretch of a heavy spring under its own weight. I have tried my best to read Doc Al's advice but I cannot figure out how to find the stretching dy on each...
