Right-angled triangle problems involving angles of elevation and depression

Reason For Learning

Sometimes a person or an object (for example, a ship or plane) changes direction during their journey. In situations like this we are usually interested in the total distance the object has moved and its final bearing from the starting point. This type of math is used by GPS apps.

Learning Intention

How angles of depression and elevation are defined. How to interpret diagrams in questions involving angles of elevation and depression. How to solve problems involving angles of depression and elevation when given a diagram. How to solve trigonometric problems in 3D
