We can use vectors to create the vector equation of a line. In order to create the vector equation of a line we use the position vector of a point on the line and the direction vector of the line. In order to find the direction vector we need to understand addition and scalar multipli...
The vector equation of a line is r = a + tb.In this equation, “a” represents the vector position of some point that lies on the line, “b” represents a vector that gives the direction of the line, “r” represents the vector of any general point on the line and “t” represent...
【题目】The vector equation of the line L is given by$$ \begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} - 3 \\ 0 \\ 8 \end{bmatrix} + t \begin{bmatrix} 4 \\ - 1 \\ - 3 \end{bmatrix} $$Show that A(5,-3,2) is the foot of the perpendicular ...
Example: Find parametric equations for the line in which the planes 3x - 6y - 2z = 15 and 2x + y - 2z = 5 intersect. From figure 12.40 we can see that the direction vector of the intersection line v is perpendicular(垂直) to the normal vector of both planes. {\bf n_1} \times...

Then the vector {eq}\mathbf{r}_1 -\mathbf{r}_0= \left<x_1-x_0, y_1-y_0,z_1-z_0\right> {/eq} is a direction vector that is parallel to the line segment, and a vector equation of the line segment is given by {eq}\mathbf{r}(t) = \mathbf{r}...
Given a vector-valued function defined by r(t)= ⎜t3+1t3+12t+1⎞⎠⎟r(t)=(t3+1t3+12t+1)Let TT denote the tangent to the curve at A=(2,2,3)A=(2,2,3).Then find the equation of the line LL passing through the point u=(1,−1,2)u=(1,−1,2),parallel...
Finally, the standard form is difficult to find and usually involves manipulating one of the other forms of the equation of a line or being given both intercepts. This leads us to the vector form for the equation of a line. As we have seen in the point–slope form, we can think of ...
