Apply the equation. to find the magnitude, which is 1.4.

Apply the equation theta = tan-1 (y/x) to find the angle: tan-1 (1.0/-1.0) = - 45 degrees. However, note that the angle must really be between 90 degrees and 180 degrees because the first vector component is negative and the second is positive.
