How do you give the complex number form of the vector with the given initial and terminal point respectively (-2, 5) and (1, 3)?
Assuming that we are given P(-2, 5) and Q(1, 3), we can use the following formula to calculate the commonly used "i and j form" of the vector:
Notice it's very similar to the slope formula, but written in point notation and using "<" instead of parentheses.
Now let's solve:
Should you want to go on to find the magnitude of the vector, you would use the formula
