Quick answer
Enter an angle in degrees to calculate sin, cos and tan together. Tangent is undefined when cosine is zero.
Common angle table
| Angle | sin | cos | tan |
|---|---|---|---|
| 0 deg | 0 | 1 | 0 |
| 30 deg | 0.5 | 0.8660254 | 0.57735027 |
| 45 deg | 0.70710678 | 0.70710678 | 1 |
| 60 deg | 0.8660254 | 0.5 | 1.73205081 |
| 90 deg | 1 | 0 | undefined |
When to use it
Use this page when the known input is an angle. If the known input is already a sine, cosine or tangent value, use a branch-aware conversion page.
