Trigonometry is the branch of mathematics that studies the relationships involving lengths of sides and measures of angles of triangles. It is a useful tool for engineers, scientists, and surveyors and is applied even in seismology and navigation. Angles. The angle AOB is a measure formed by two rays OA and OB sharing the common point O as shown below. The common point O is called the vertex.
The fields that trigonometry is being used today for include electronics, engineering, and calculus. A study of trigonometry will primarily involve concepts of angles, the right triangle, and the unit circle. The problems you can solve with trigonometry are many. A short list includes the following: Angle of elevation. Angle of depression.
