### Unit Tangent and Normal Vectors for a Helix

Multivariable Calculus: Find the unit tangent vector T(t), unit normal vector N(t), and curvature k(t) of the helix in three space r(t) = (3sint(t), 3cos(t), 4t). We also calculate the unit binormal vector B(t). For more videos like this one, please visit the Multivariable Calculus playlist at my channel.
