Trigonometric Functions

  • Sine: sin(θ) = opposite/hypotenuse
  • Cosine: cos(θ) = adjacent/hypotenuse
  • Tangent: tan(θ) = opposite/adjacent
  • Cosecant: csc(θ) = 1/sin(θ)
  • Secant: sec(θ) = 1/cos(θ)
  • Cotangent: cot(θ) = 1/tan(θ)

Common Values

  • 0°: sin=0, cos=1, tan=0
  • 30°: sin=0.5, cos=0.866, tan=0.577
  • 45°: sin=0.707, cos=0.707, tan=1
  • 60°: sin=0.866, cos=0.5, tan=1.732
  • 90°: sin=1, cos=0, tan=∞
