i want to use the new point's (c) coordinates but how can i correct this? thank you for helps.

a:=point([1,0,0],color=red,thickness=6):

c:=animate([rotate[a,alpha,[[0,0,0],[px,py,pz]]]],g2=0..2*Pi):

cx,cy,cz:=animate([op[c][]],g2=0..2*Pi):                                                                                                                                        

Error, cannot split rhs for multiple assignment

Hi!

How can i find of the intersection two great circles on the sphere?

Thanks...

h1:=spacecurve({[x,y,z]},t=0..Pi,scaling=constrained,color=blue,thickness=3):
h6:=rotate(h1,a5, [[0,0,0],[n1,n2,n3]]):

i have rotated a point on the sphere with rotate command. i found the new points coordinates but I can not use them. How can I use the new coordinates?
thanks..
