In this class we are going to be using a global 360 definition of a direction.

In this class we are going to be using the trig functions of cos, sin, and tan beyond the 1st quadrant where local angles are typically taught.

Instead of figuring the projections given an angle, we also need to determine which angles will give us the given projections.

Determine the distance between the ends of two lines given angle angle between the two lines.

It is important to determine the coordinates location of points for a given structure.

Applying the skills learned, we can not determine the global direction of a line!
