Homework Help: AP Physics

Posted by Paige on Thursday, August 30, 2012 at 4:55pm.

Consider the vectors A = 2.00 i + 7.00 j and B = 3.00 i - 2.00 j.

(a) Sketch the vector sum C = A + B and the vector subtraction D = A - B.

(b) Find analytical solutions for C and D first in terms of unit vectors and then in terms of polar coordinates, with angles measured with respect to the positive x axis.

I just can't figure out what the degree should be for the D vector polar coordinate
