In Los Angeles schools, Trigonometry is initially taught as part of the Algebra 2 curriculum and then developed more during Pre-Calculus or Math Analysis course. However, there are school that offer Trigonometry as a stand alone course. Trigonometry is informally called "trig".

Tutoring in Los Angeles can assist your student with an expert Trigonometry tutor to facilitate your student incursion in the fascinating world of math.

Trigonometry (from Greek trigo-non "triangle" + metron "measure") is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles).

Trigonometry is concerned with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships. There are 6 basic trigonometric functions: sine, cosine, tangent, cotangent, secant and cosecant. Their values are interconnected and that makes trigonometry almost poetic. An important topic in Trigonometry deals with trigonometric identities.

Trigonometry has applications in both pure mathematics and in applied mathematics, where it is essential in many branches of science and technology, including:

- Architecture:Trigonometry is used to calculate the height of buildings, bridges, and other structures. It helps architects and engineers determine the optimal design and ensure stability.
- Astronomy:Trigonometry is essential for calculating distances and positions of celestial bodies, such as planets and stars. It helps astronomers determine the orbits and trajectories of these objects.
- Surveying:Trigonometry is used to calculate the distances and angles between landmarks and reference points, enabling surveyors to create accurate maps and determine property boundaries.
- Navigation:Trigonometry is used in navigation systems, such as GPS, to calculate the user’s location and velocity. It helps pilots, sailors, and drivers determine their position and course.
- Physics:Trigonometry is used to describe the motion of objects, including the trajectory of projectiles and the behavior of waves.
- Engineering:Trigonometry is applied in various engineering fields, such as mechanical, electrical, and civil engineering, to design and analyze systems, mechanisms, and structures.
- Criminology:Trigonometry is used in forensic science to calculate the trajectory of bullets and determine the position of crime scenes.
- Aviation:Trigonometry is used in aircraft navigation and flight planning to calculate routes, altitudes, and velocities.
- Geology:Trigonometry is used to calculate the orientation and dip of rock layers, helping geologists understand the Earth’s structure and history.
