start with model rockets first

Well today in class, we were talking about galaxies and orbits and the radius of black holese and how every black hole is at the center of a galaxy. Then i got to thinking, what causes the spin of a galaxy, and this led me to thinking, is there a way to find out the torque of a spinning galaxy...

can't he plug in -1 for to zero out A and get B (heaviside cover up method?)

thank you very much, i just needed clarification on that part of the equality

curved E ish symbol= all real numers? edit so what it means that "increasing" or "decreasing" has a point where a(n) is equal to a(n+1)? but strictly inc/dec means that no matter what value 'n' is, a(n) will always be > or < a(n+1) correct?

that v symbol means "for all n " correct?

What exactly is the difference between "increasing/decreasing" and "strictly increasing/decreasing" ? is it similar to conditional and absolute convergence?

Homework Statement A string is wrapped several times around the rim of a small hoop with radius 8.00 cm and mass 0.180 kg . The free end of the string is held in place and the hoop is released from rest (the figure ). After the hoop has descended 60.0 cm, calculate angular speed and...

it'd cost a lot of money to do that.
