Trigonometry
Trigonometry studies relationships between the sides and angles of triangles. It introduces the sine, cosine, and tangent functions and extends them to the unit circle, inverse trig functions, and trigonometric identities. Trigonometry is essential for physics, engineering, navigation, and is a key prerequisite for calculus.
