Question

For the vector \[\vec{P_1P_2}\], which point is the initial point?

Options

• \[P_1\]

• Neither \[P_1\] nor \[P_2\]

• \[P_2\]

• Both \[P_1\] and \[P_2\]

Answer 1

In \[\vec{P_1P_2}\], the vector starts at \[P_1\] and ends at \[P_2\]. Thus, \[P_1\] is the initial point and \[P_2\] is the terminal point.
