Trigonometry focuses on relationships among angles, triangle sides, and corresponding ratios.
Trigonometry is a branch of mathematics that studies relationships between angles and side lengths, especially in triangles. It begins with trigonometric ratios in right triangles, including sine, cosine, and tangent, which depend on the measure of an angle. Their reciprocals are cosecant, secant, and cotangent. These functions can also be defined using the unit circle, allowing them to apply to positive and negative angles and to real or complex numbers. The scope of trigonometry extends beyond basic triangle calculations to include inverse functions, identities, laws for solving arbitrary triangles, spherical trigonometry, periodic functions, power series, and connections with complex exponentials. It is widely used in astronomy, navigation, surveying, engineering, physics, acoustics, optics, signal processing, computer graphics, medical imaging, and many other fields.
