Calculateur de Sine, Cosine, Tangent
Calculate sine, cosine, and tangent of an angle in degrees.
Formula and method
This calculator computes sin, cos, tan directly in your browser without sending data to an external server.
Mathematical formula
- sin:
Math.sin(angleDeg × π ÷ 180) - cos:
Math.cos(angleDeg × π ÷ 180) - tan:
Math.tan(angleDeg × π ÷ 180)
Variables and parameters
- Angle (angleDeg): default value 45 deg.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
