Given that point A, B, C, E are (0,0,6), (-1,-7,11), (-8,-6,6) and (15,-20,6). BD is horizontal and parallel to AE. Find a vector equation of the line BD. Given that the length of BD is 15 metres, find the coordinates of D. How to do?
The vector equation of the line
# bb(ul r) = ( (-1),(-7),(11) ) + lamda ( (3),(-4),(0) )#
We have the following coordinates:
Using vector notation, we have:
Similarly:
From this we can establish that:
Hence, we have:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
