1
sin(u - v)
sin(u)cos(v) + cos(u)sin(v)
sin(u)sin(v) + cos(u)cos(v)
sin(u)cos(v) - cos(u)sin(v)
sin(u)sin(v) - cos(u)cos(v)
2
tan (75)
(1 - √3)/(√3 + 1)
√3
1/√3
(1 + √3)/(√3 - 1)
3
sin (x + π)
sin x
- cos x
-sin x
0
4
cos(π/3)cos(π/4) + sin(π/3)sin(π/4)
cos(2π/7)
cos (7π/12)
sin(π/12)
cos (π/12)
5
sin (135)
(√2+2)/2
(√2)/2
(√2)/2+1
-(√2)/2
6
cos(π/2 - x)
sin x
cos x
cos (π/2)
sin (π/2)
7
sin (π/2 - x)
sin (π/2)
cos x
sin x
cos (π/2)
8
cos (π/12)
(√2+√6)/4
(2+√3)/4
(√2-√6)/4
(2-√3)/4
9
cos(u-v)
cos(u)cos(v)+sin(u)sin(v)
cos(u)cos(v)-sin(u)sin(v)
cos(u)sin(v)+sin(u)cos(v)
cos(u)sin(v)-sin(u)cos(v)
10
Tan(u - v)
(tan(u)+tan(v))/(1-tan(u)(tanv))
(tan(u)-tan(v))/(1-tan(u)(tanv))
(tan(u)+tan(v))/(1+tan(u)(tanv))
(tan(u)-tan(v))/(1+tan(u)(tanv))
