Lines in 3D
In the 3D coordinate organisation, lines tin be described using vector equations or parametric equations. Lines in 3D take equations like to lines in 2D, and can be found given 2 points on the line. In lodge to understand lines in 3D, i should empathise how to parameterize a line in second and write the vector equation of a line. Perpendicular, parallel and skew lines are important cases that arise from lines in 3D.
3D equations of lines and planes
1. Equation of a second line in vector, parametric and symmetric forms.
2. Equation of a 3D line in vector, parametric and symmetric forms.
3. Equation of a plane in vector (passing mention) and Cartesian grade.
iv. Three methods for finding the line of intersection of 2 planes.
Including examples in all 4 parts, and a quick method for obtaining the cross product.

Parallel and Skew Lines in Infinite
With the introduction of the 3D coordinate system we find the concepts of skew, perpendicular and parallel lines in space. Skew lines are new, and are lines that are not parallel, yet never intersect. Perpendicular and parallel lines in space are very similar to those in 2nd and finding if lines are perpendicular or parallel in infinite requires an agreement of the equations of lines in 3D.
