Vectors are quantities that possess both magnitude and direction. In engineering problems, it is best
to think of vectors as arrows, and usually it is best to manipulate vectors using components. In this
tutorial, we consider the addition of two vectors using both of these techniques.
Consider two vectors A and B that have lengths A and B, respectively. Vector B makes an angle
from the direction of A. (Figure 1)In vector notation, the sum is represented by
C = A +B
where C is a new vector that is the sum of A and B.

Follow-up Question

When I place the law of cosines formula in for C=, it states that I have to have an argument in the paranthesis with the cos. I'm assuming the cosine formula is the answer, but not exactly understanding what it's asking for with it having no numbers. Thank you for your feedback.
