Question
Find (a) parametric equations and (b) symmetric equations of the line. The line through (2,1,3) and (4,0,4)
Step 1
This can be found by subtracting the coordinates of the two given points. Let's denote the points as $P_1(2,1,3)$ and $P_2(4,0,4)$. The direction vector $\vec{v}$ is then given by $\vec{v} = P_2 - P_1 = (4-2, 0-1, 4-3) = (2, -1, 1)$. Show more…
