You will now find the same quantity algebraically, without the need to use much geometry. Take the north direction as the positive y direction and east as positive x. The origin is still where the student starts biking.

Let d_vec_N be the displacement vector corresponding to the first leg of the student's trip. Express d_vec_N in component form.

Express your answer as two numbers separated by a comma (e.g., 1.0,2.0). By convention, the x component is written first.

**Lacey**, Friday, September 24, 2010 at 1:17pmI figured this out. For those that may need help with a question like this. Because of the North direction being the displacement vector... there was a 90 degree angle. So...

(1.1)(cos90) = 0

(1.1)(sin90) = 1.1

Answer: (0, 1.1)
