Answer 2

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. ...

• Pythagorean: I tan = get sic. ...

• Pythagorean: I cut = crescent rolls.
