x = -22*cos(t) - 128*sin(t) - 44*cos(3*t) - 78*sin(3*t) y = 11*cos(t) - 43*cos(3*t) + 34*cos(5*t) - 39*sin(5*t) z = 70*cos(3*t) - 40*sin(3*t) + 8*cos(5*t) - 9*sin(5*t)
x = m*cos(a*t) + n*cos(b*t) y = m*sin(a*t) + n*sin(b*t) z = h*sint(c*t)
x = cos(2*t) + 0.25*cos(-7*t) y = sin(2*t) + 0.25*sin(-7*t) z = 0.35*sin(9*t)
x = 1.50*cos(t) + 0.35*cos(3*t) - 0.90*cos(5*t) y = sin(t) + 0.35*sin(3*t) - 0.90*sin(5*t) z = 0.35*sin(8*t) - 0.20*sin(2*t)
x = cos(2*t) + 0.67*cos(7*t) y = sin(2*t) + 0.67*sin(7*t) z = 0.20*sin(10*t) - 0.10*sin(5*t)
