Question

What is the midpoint between `A(1,1,1)` and `B(4,1,-3)`?

Answer 1

The answer is `M(5/2,1,-1)`.

The midpoint is one of the easier things to calculate. Remember that mid is a synonym for average. To find the midpoint, we just average the components:

`M=((P_(1_x)+P_(2_x))/2, (P_(1_y)+P_(2_y))/2, (P_(1_z)+P_(2_z))/2)`
