📐 Trigonometry Calculator

A trigonometry calculator is a tool that helps you calculate trigonometric function values (sine, cosine, tangent) and solve triangle problems using trigonometric relationships.

Enter an angle in degrees or radians, and the calculator will instantly provide all six trigonometric function values: sin, cos, tan, csc, sec, and cot.

Yes, you can input any two known parameters (sides, angles, or area) and the calculator will determine all missing triangle measurements using trigonometric relationships.

Degrees divide a circle into 360 parts, while radians use the circle's radius as the unit. One full circle equals 360° or 2π radians. Use the unit toggle to switch between them.

The calculator provides results accurate to 8 decimal places using standard mathematical functions, suitable for most educational and professional applications.

SOHCAHTOA is a mnemonic for remembering trigonometric ratios: Sin = Opposite/Hypotenuse, Cos = Adjacent/Hypotenuse, Tan = Opposite/Adjacent.

No, you need at least one side length to determine the actual size of the triangle. Angles alone only determine the triangle's shape, not its scale.

Trigonometry is used in engineering, physics, astronomy, navigation, architecture, computer graphics, and many other fields requiring angle and distance calculations.
