Enter an angle in degrees or radians to get all six trigonometric values: sin, cos, tan, sec, csc, and cot.
Trigonometric Values
Trigonometric Functions relate angles to ratios of sides in a right triangle.
Six functions:
sin(θ)= opposite / hypotenusecos(θ)= adjacent / hypotenusetan(θ)= opposite / adjacent = sin(θ) / cos(θ)csc(θ)= 1 / sin(θ)sec(θ)= 1 / cos(θ)cot(θ)= 1 / tan(θ) = cos(θ) / sin(θ)
Conversion:
Radians = Degrees × π / 180Degrees = Radians × 180 / π
Common angles:
| Degrees | Radians | sin | cos | tan |
|---|---|---|---|---|
| 0° | 0 | 0 | 1 | 0 |
| 30° | π/6 | 0.5 | 0.866 | 0.577 |
| 45° | π/4 | 0.707 | 0.707 | 1 |
| 60° | π/3 | 0.866 | 0.5 | 1.732 |
| 90° | π/2 | 1 | 0 | undefined |
