|
Sum and Difference Formulas (Sin) [5.2] |
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B – cos A sin B |
|
|
Sum and Difference Formulas (Cos) [5.2] |
cos (A + B) = cos A cos B – sin A sin B
cos (A - B) = cos A cos B + sin A sin B |
|
|
Double Angle Formulas (Sin) [5.3] |
sin 2A = 2 sin A cos A |
|
|
Double Angle Formulas (Cos) [5.3] |
(1st form) cos 2A = cos² A – sin² A
(2nd form) cos 2A = 2 cos² A – 1
(3rd form) cos 2A = 1 – 2 sin² A |
|
|
Cofunction Theorem [2.1] |
sin x = cos (90º – x)
cos x = sin (90º – x)
tan x = cot (90º – x) |
|
|
Half-Angle Formulas [5.4] |
|
|
|
Law of Sines [7.1] |
(sin A) / a = (sin B) / b = (sin C) / c |
|
|
Law of Cosines [7.2] |
a² = b² + c² – 2bc cos A
b² = a² + c² – 2ac cos B
c² = a² + b² – 2ab cos C
