    up = radius sin(pi/6) if im reading this right

    sph (radius, theta, phi) where theta is from the x axis and phi from the z?

    from (p,t,f) to (r,t,z), this is for my own recollection, lets see if we can get to the -4 :) r = p cos(f) t = t z = p cos(f) so the -4 is just -4 in both cases

    your not asked to analyse -4, your simply told to put this into cyl coords; so -4 gets transfered as is

    and yes, all angles are radian measures at this point unless they specifically tell you otherwise
