## Homework Statement

**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

(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.

## Homework 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.

## 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?
