Trigonometry

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles, particularly right triangles. It defines functions such as sine, cosine, and tangent to model periodic phenomena and solve geometric problems. This foundational concept is widely applied in fields like physics, engineering, computer graphics, and navigation.

Why learn Trigonometry?

Developers should learn trigonometry for tasks involving geometry, simulations, game development, and signal processing, such as calculating rotations, trajectories, or wave patterns. It is essential in computer graphics for 3D rendering, animation, and physics engines, and in data science for analyzing cyclical data like time series or audio signals.
