Understanding This Calculator

Trigonometric Functions

Fundamental ratios in a right-angled triangle.

  • Sine (sin) = Opposite / Hypotenuse
  • Cosine (cos) = Adjacent / Hypotenuse
  • Tangent (tan) = Opposite / Adjacent

Example 1

Angle: 30°

  • sin(30°) = 0.5
  • cos(30°) ≈ 0.866
  • tan(30°) ≈ 0.577

Example 2

Angle: 45°

  • sin(45°) ≈ 0.707
  • cos(45°) ≈ 0.707
  • tan(45°) = 1.0

How to Use

  • Enter an angle value.
  • Choose degrees or radians.
