AHL 3.18
To find the intersection of a line and a plane, substitute the vector line equation into the plane equation and solve for the parameter λ.
For example, suppose we have the line:
and the plane:
Substituting the line into the plane gives:
Expanding:
Substituting this back into the line gives the intersection point:
