I have a question on an assignment that expects the I+J form of a vector but is only giving the direction(cardinal) or angle of the vector. See example below: 1. The problem statement, all variables and given/known data Unit vectors and are directed east and north, respectively. Calculate the unit vector (in terms of I and J) in the following directions. (a) northeast (b) 47° clockwise from the -y axis (c) southwest All answers demand an I + J response and I'm can't exactly figure out what it wants or where to even start without a scalar. 2. Relevant equations Finding the I+J components with an angle of direction can be determined by using trigonometric functions to solve for components of the resulting reference right triangle. 3. The attempt at a solution For the (a) problem, I tried putting in s for scale and tried a few different pseudo type answers but was not successful. e.g. rcos(45)i + rsin(45)j Has anyone seen problems like this particular one or have any ideas on what it's asking for?
