So if I evaluatev(0)→|v(0)→|I should be able to get the unit tangent vector at the desired point. Yes, the unit tangent isv(0)→|v(0)→|. However, you made finding v(t) more complicated than necessary and I don't think you got it right in the end. Factor out a -e^(...
Thus, Ui (i = 1, 2, 3) is the unit vector field in the positive xi direction. 2.5 Lemma If V is a vector field on R3, there are three uniquely determined real-valued functions, v1, v2, v3 on R3 such that V=v1U1+v2U2+v3U3. The functions v1, v2, v3 are called the Eucli...
It has a hat because it's a unit vector, and t because it's tangent. 这上面有一个帽子表示它是单位矢量,T表示它是切线。 So, the velocity vector is going to be always tangent to the curve. 速度向量总是与曲线相切的。 If we were moving on the tangent plane, this would be an actua...
While the actual direction of the object (and thus, of the velocity vector) is changing, its direction is always tangent to the circle. To summarize, an object

(Hint: In the usual ruled parametrization (u, 0, 0) + v(0, 1, u), this last vector must be replaced by a unit vector in order to apply Ex. 11. The curvature formula in Ex. 4.3 will then change.)13.If x(u, v) = α(u)...
1.0 1.0 Rather than i and j, many times it would be better to get the unit 2 vectors shown above, one parallel to the velocity vector and the other perpendicular to the velocity vector. We can get a unit vector in the direction of motion- it is the vector called The Unit Tangent ...
