Hi y'all. Carlo T here with a little mathematical puzzler.
Here's the big ol' question, are you folks ready?
let phi:(0, infty)x(0, 2*pi)x(-pi/2, pi/2)->R^3 be defined by
phi(r,alpha,beta)=(r*cos(alpha)*cos(beta), r*sin(alpha)*cos(beta), r*sin(beta)).
Calculate the pullback phi*(xdy)
I've calculated phi*(dx), phi*(dy) and phi*(dz) but am not sure where to go from here.
For example, is there a way of rewriting phi*(xdy) using one of the pullback properties?
Get your noggins round that one brothers.
Peace out, from the C to the T to the remBath!
