这都是根据题目要求而定的，有一个问题是，找出向量的分量就足够了吗？，还是说我们需要解出一条直线的方程？

It depends what the problem is asking the question is, is it enough to find the components of a vector or do we have to find the equation of a line?

所以通常在空间中，不会要求去画出向量场。

Usually, in space, we won't really try too hard.

这是另一种形式，它意味着,要求出每点处向量在切向量方向的分量,我还是用之前那个向量场吧。

That is how we reformulated it. That means we take our curve and we figure out at each point how big the tangent component I guess I should probably take the same vector field as before.
