The unit binormal vector, g, is the cross product of the unit tangent vector and the principal unit normal vector: B(t) = F(t) x Ñ(t) Question 8 Compute the unit binormal vector for each curve below: A) F(t) = , where R is a positive constant. B) F(t) = <2* cos(t), 2* sin(t), t>. Simplify your answer algebraically as far as you can. SHOW WORK.
