TRIG IDENTITIES
| cos 2 x + sin 2 x = 1 | sec 2 x = 1 + tan 2 x |
| csc 2 x = 1 + cot 2 x | cos 2 x = ½ (1 + cos 2x) |
| sin 2 x = ½ (1 - cos 2x) | sin 2x = 2 sin x cos x |
| cos 2x = cos 2 x - sin 2 x cos 2x = 1 - 2 sin 2 x cos 2x = 2 cos 2 x - 1 |
 |
.
PRODUCT FORMULAS
| sin u cos v = ½ [sin (u + v) + sin (u - v)] | cos u sin v = ½ [sin (u + v) - sin (u - v)] |
| cos u cos v = ½ [cos (u + v) + cos (u - v)] | sin u sin v = ½ [cos (u - v) - cos (u + v)] |
