Find parametric equations for the tangent line at the point (cos(-4pi/6),sin(-4pi/6),-4pi/6) on the curve x=cost, y=sint,z=t
x(t) = _________
y(t) = _________
z(t) = _________
r'(t) = <-sin(t), cos(t), 1>
r'(0) = <0,1,1>
my answer:
x = cos(-4pi/6) + 0t
y = sin(-4pi/6) +1t
z = -4pi/6 +t
the only part i got correct is the z, anyone know what im doing wrong?
