| Question | Answer |
|---|---|
| tan(x) | sin(x)/cos(x) |
| cot(x) | cos(x)/sin(x) |
| sec(x) | 1/cos(x) |
| csc(x) | 1/sin(x) |
| sin(x) | 1/csc(x) |
| cos(x) | 1/sec(x) |
| tan(x) | 1/cot(x) |
| 1 | sin(x)^2 + cos(x)^2 |
| csc(x)^2 | 1+cot(x)^2 |
| sec(x)^2 | tan(x)^2 + 1 |
| -sin(x) | sin(-x) |
| cos(x) | cos(-x) |
| -tan(x) | tan(-x) |
| -csc(x) | csc(-x) |
| sec(x) | sec(-x) |
| -cot(x) | cot(-x) |
