| cos (π + x) | – cos x |
| sin (π + x) | –sin x |
| cos (2π – x) | cos x |
| sin (2π – x) | –sin x |
| tan(x+y) | tanx+tany / 1-tanxtany |
| tan(x-y) | tanx-tany / 1+tanxtany |
| cot(x+y) | cotxcoty-1 / coty+cotx |
| cot(x-y) | cotxcoty+1 / coty-cotx |

| 2cosxcosy | cos(x+y) + cos(x-y) |
| -2sinxsiny | cos(x+y) - cos(x-y) |
| 2sinxcosy | sin(x+y) + sin(x-y) |
| 2cosxsiny | sin(x+y) - sin(x-y) |
| sinx = 0 | →x = nπ |
| cosx = 0 | →x = (2n+1)(π/2) |
| sin x = sin y | ⇒ x = nπ + (–1)^n y |
| cos x = cos y | ⇒ x = 2nπ ±y |
| tan x = tan y | ⇒ x = nπ + y |
| 2sin^2 X/2 | 1 - cosx |
| 2cos^2 x/2 | 1 + cosx |
| tan θ/2 | 1-cosθ / sinθ |
| sin(A+B) sin(A-B) | :sin^2 A - cos^2 B :cos^2 B - cos^2 A |
| cos(A+B) cos(A-B) | :cos^2 A - sin^2 B :-sin^2 A + cos^2 B |
| tan(A+B) tan(A-B) | tan^2 A-tan^2 B / 1-tan^2 A tan^2 B |
| Sine Formula | sinA/a = sinB/b = sinC/c = k |
| Cosine Formula | :a^2 = b^2 + c^2 -2bccosA :b^2 = c^2 + a^2 -2cacosB :c^2 = a^2 + b^2 -2abcosC :CosA = (b^2 +c^2 -a^2)/2bc :CosB = (c^2 +a^2 -b^2)/2ac :CosC = (a^2 +b^2 -c^2)/2ab |
