Reciprocal: csc(θ) = csc(θ) = 1/sin(θ)

Reciprocal: sec(θ) = sec(θ) = 1/cos(θ)

Reciprocal: cot(θ) = cot(θ) = 1/tan(θ)

Ratio: tan(θ) = tan(θ) = sin(θ)/cos(θ)

Ratio: cot(θ) = cot(θ) = cos(θ)/sin(θ)

Pythagorean: sin costs = $1. …

Pythagorean: I tan = get sic. …

Pythagorean: I cut = crescent

cosec(θ) = 1/sin(θ)

sec(θ) = 1/cos(θ)

cot(θ) = 1/tan(θ)

tan(θ) = sin(θ)/cos(θ)

cot(θ) = cos(θ)/sin(θ)

(sinθ)^2 + (cosθ)^2=1

1 + (tanθ)^2 = (secθ)^2

1 + (cotθ)^2 = (coscθ)^2
