Study Notes

Trigonometry Overview

Study of triangles and the relationships between their sides and angles is known as trigonometry.

Trigonometric Functions

Sine function (sin) represents the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right-angled triangle.
The reciprocal of the sine function is called the cosecant function (csc).
Cosine function (cos) represents the ratio of the length of the side adjacent to the angle to the length of the hypotenuse in a right-angled triangle.
The reciprocal of the tangent function is known as the cotangent function (cot).
A crucial trigonometric identity relating sine and cosine functions is sin²(θ) + cos²(θ) = 1 for any angle θ.
