Given the vectors = 2.00 + 8.00 and = 4.00  5.00, do the following.
(a) Draw the vector sum = + and the vector difference =  . (Do this on paper. Your instructor may ask you to turn the paper in.)
(b) Calculate and , first in terms of unit vectors.
Calculate and in terms of polar coordinates, with angles measured with respect to the +x axis.

vectors have direction. YOu have specified no directional vectors in your vectors.

Given the vectors A = 2.00i + 8.00j and B = 4.00i  5.00j, do the following.
(a) Draw the vector sum C= A+ B and the vector difference D= A B.
(b) Calculate C and D, first in terms of unit vectors.
Calculate C and D in terms of polar coordinates, with angles measured with respect to the +x axis.
