This category contains pages concerning Equation of Straight Line in Space/Parametric Form:
Let $\LL$ be a straight line embedded in a cartesian $3$-space passing through the point $\tuple {x_1, y_1, z_1}$ and with direction cosines $l$, $m$ and $n$.
$\LL$ is expressed in parametric form by the set of equations:
- $\begin {cases} x & = & x_1 + l d \\ y & = & y_1 + m d \\ z & = & z_1 + n d \end {cases}$
where $d \in \R$ is the distance of the variable point $\tuple {x, y, z}$ from $\tuple {x_1, y_1, z_1}$
