SOLUTION: How do I solve? For the vector U = <3,-2> and V = <-5,1>, determine the magnitude and direction (angle with x-axis) of the following: A) U-V B) V-U C)U+3V D) 2V-3U I woul

Question 1078137: How do I solve? For the vector U = <3,-2> and V = <-5,1>, determine the magnitude and direction (angle with x-axis) of the following:
A) U-V
B) V-U
C)U+3V
D) 2V-3U
I would appreciate any help please and thanks!

U = <3,-2> and V = <-5,1>
:
A) U - V = <3,-2> - <-5,1> = <8, -3>
:
B) V - U = <-5,1> - <3,-2> = <-8, 3>
:
C) U + 3V = <3,-2> + <-15, 3> = <-12, 1>
:
D) 2V-3U = <-10, 2> - <9, -6> = <-19, 8>
