(b) use formula 9 to find the curvature. 𝐫(t)= t, 1 2 t^2, t^2 watch the full vide.
Unit Tangent Vectors Youtube In this video, we close off the last topic in calculus ii by discussing the last topic, which is the idea of unit tangent, normal and the bi normal vectors. The unit tangent vector t(t) of a vector function is the vector that’s 1 unit long and tangent to the vector function at the point t. remember that |r'(t)| is the magnitude of the derivative of the vector function at time t. the unit normal vector n(t) of the same vector function is the ve. To find the unit tangent vector for a vector function, we use the formula t (t)= (r' (t)) (||r' (t)||), where r' (t) is the derivative of the vector function and t is given. we’ll start by finding the derivative of the vector function, and then we’ll find the magnitude of the derivative. those two values will give us everything we need in. The principal unit normal vector. a normal vector is a perpendicular vector. given a vector v in the space, there are infinitely many perpendicular vectors. our goal is to select a special vector that is normal to the unit tangent vector.

Alright, so now that we know what the tnb vectors are, let’s look at an example of how to find them. suppose we are given the circular helix r → (t) = t, cos t, sin t . first, we need to find the unit tangent for our vector valued function by calculating r → ′ (t) and ‖ r → ′ (t) ‖. r → ′ (t) = 1, − sin t, cos t ‖ r →. The tangent line at a point is calculated from the derivative of the vector valued function r(t) r (t). notice that the vector r′(π 6) r ′ (π 6) is tangent to the circle at the point corresponding to t = π 6 t = π 6. this is an example of a tangent vector to the plane curve defined by r(t) = costi sintj r (t) = cos t i sin t j.
