    Force applied on a rotating disc

    I understand that if we apply a force on the axis of rotation of a spinning disc, the torque is in a different direction, and the axis is moved in a direction perpendicular to the direction in which the force upon the axis was applied, determined by the right-hand rule. But what if the force...

    Why do orbits become more eccentric when changing speed?

    From what I understand (and also assuming that the mass of one body is much greater than the other), if we had a body performing a circular orbit, and we put more (or less?) energy into the orbit by changing the speed of the body, the orbit will become more eccentric, i.e. elliptical. My...

    Mathematica Mathematica - Showing iterations graphically

    I'm trying to do this: Suppose I have some iterative function $x_{n+1}=\sin(x_n)$. I want to demonstrate an iteration on a plot by graphing $y=\sin(x)$ and $y=x$, then drawing lines from the graph of x to the graph of sin x, like in this page...

    Mathematica Mathematica - Iterations with 2 arguments

    I see. It works great, thank you very much!

    Mathematica Mathematica - Iterations with 2 arguments

    I'm trying to build a simple function that takes 2 arguments. Basically, I want it to do this: x(n+1)=a*sin[x(n)] and generate a list of x0,x1,x2 etc. up to x(n) like NestList does, starting from x0=1.0 So I want to make a list of these iterations, where a is a constant of my choice...
