Your post was incrdibly helpful! I understand it all now thank you for doing the diagrams also.

Kind Regards

]]>You have a length of 6 at an angle of 120 degrees. To describe the point in rectangular form, you need to find the horizontal and vertical distance from the origin. Here, you can draw a 60 degree right triangle with a hypotenuse of 6 units. So all you have to do is find the length of the horizontal and vertical sides to get the horizontal and vertical distance from the origin. You can do this using similar triangles or trig functions (sine and cosine). Also note, in this example, the horizontal side of the triangle I drew, will have a length of 3, however, this is 3 units to the LEFT of the origin, therefore its x coordinate will be -3 and not 3.

I have no idea how to start doing these? Guidence of any kind would be wonderful.
