CASTESIAN (tuka)
a(u,v,t)= 5*cos(u)*cos(u+v)
R(u,v,t)= 5*cos(u)*sin(u+v)
Z(u,v,t)= 5*sin(u)
min U = -5 max U = 5 steps = 50
min v = -5 max v = 5 steps = 35
CARTESIAN (buka)
a(u,v,t)= (u+v)*sin(u-v)*0,.5
R(u,v,t)= (u+v)*cos(u-v)*0.5
Z(u,v,t)= u-v
min U = -4 max U = 4 steps = 50
min v = -4 max v = 4 steps = 50
