Definition of cotangent (cot)

Back

Cotangent is the reciprocal of tangent: cot(θ) = 1/tan(θ).

Definition of sine (sin)

Back

Sine is the ratio of the opposite side to the hypotenuse in a right triangle: sin(θ) = opposite/hypotenuse.

Front

Definition of cosine (cos)

Back

Cosine is the ratio of the adjacent side to the hypotenuse in a right triangle: cos(θ) = adjacent/hypotenuse.
