| sin^2(x) + cos^2(x) = | 1 |
| tan^2(x) + 1 = | sec^2(x) |
| 1 + cot^2(x) = | csc^2(x) |
| 2sin(x)cos(x) = | sin(2x) |
| cos^2(x) - sin^2(x) = | cos(2x) |
| 0.5(1-cos(2x)) = | sin^2(x) |
| 0.5(1+cos(2x)) = | cos^2(x) |
| sin(pi/2-x) | cos(x) |
| cos(pi/2-x) | sin(x) |
| d/dx (ln|sec(x)| +C) | tan(x) |
| d/dx (ln|sec(x)+tan(x)| +C) | sec(x) |
