Sin Cos Tan Calculator
Calculate sine, cosine, tangent, cotangent, secant, and cosecant for an angle in degrees, radians, pi-radians, or DMS, with exact unit-circle values when available.
Sin, cos, and tan for an angle
English search intent for a sin cos tan calculator is a quick trigonometric function lookup. Users enter an angle, choose degrees or radians, and expect sine, cosine, tangent, and often reciprocal functions.
theta is the input angle. Tangent is undefined when cosine is 0.
Inputs and outputs
- Degree, decimal-radian, pi-radian, and DMS angle inputs.
