Calculating Vectors Example 1 (Finding Magnitude and Direction) | Introduction to Physics

In this video I walk through an example of how to calculate the magnitude and direction of a vector when given the starting and ending points of the vector and it's angle direction.

I realize I made an error when calculating Px and Py. Technically it should be the end point minus the starting point (i.e. -2 - 0 for x, and 5 - 0 for y). Since the starting point of the vector is (0, 0) the answer still worked out the same, but if the starting point was anything other than zero it would be incorrect.
