Both sin and cos range between 1 and -1. They start at different values.
The tangent ranges from zero to infinity. For all of the functions, you can get a good idea by rotating a radius (hypotenuse) of 1 counterclockwise around the origin (x and y axes).
For instance:
| Degrees | 0 | 30 | 45 | 60 | 90 | 120 | 135 | 150 | 180 | 210 | 225 | 240 | 270 | 300 | 315 | 330 | 360 |
