Question

What all are trigonometric identities

Answer 1

Answer:

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. (sinθ)^2 + (cosθ)^2 = 1.

Pythagorean: I tan = get sic.

Pythagorean: I cut = crescent rolls.
