Trigonometric Functions

1. Fundamental trigonometric identities

   • Ratio: cot(θ) = cot(θ) = cos(θ)/sin(θ)
   • Pythagorean: sin costs = $1
   • Pythagorean: I tan = get sic 1 + (tanθ)^2 = (secθ)^2
   • Pythagorean: I cut = crescent rolls 1 + (cotθ)^2 = (cscθ)^2
   • 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)
