Understanding Trigonometric Functions

Trigonometry is the study of relationships between side lengths and angles of triangles. This calculator makes solving those relationships simple.

Core Functions

  • Sine (sin): Ratio of the opposite side to the hypotenuse.
  • Cosine (cos): Ratio of the adjacent side to the hypotenuse.
  • Tangent (tan): Ratio of the opposite side to the adjacent side.

Degrees vs. Radians

Most real-world measurements use Degrees (a full circle is 360°), which is why our Trigonometry Calculator defaults to DEG mode. However, for calculus and higher math, you can switch to RAD mode with one click. Remember: 180° = π radians.

Applications

Use this tool for physics vector components, construction calculations (roof pitches, ramps), and navigation problems.
