25
csc e cot (fórmula)
cot^2+1=csc^2
26
sin(a+b) =
sin(a)cos(b)+cos(a)sin(b)
27
sin(a-b) =
sin(a)cos(b)-cos(a)sin(b)
28
cos(a+b) =
cos(a)cos(b)-sin(a)sin(b)
29
cos(a-b) =
cos(a)cos(b)+sin(a)sin(b)
30
tan(a+b) =
tan(a)+tan(b) / 1-tan(a)tan(b)
31
tan(a-b) =
tan(a)-tan(b) / 1+tan(a)tan(b)
32
sin(a)sin(b) =
1/2 [cos(a-b)-cos(a+b)]
33
sin(a)cos(b) =
1/2 [sin(a+b)+sin(a-b)]
34
cos(a)cos(b) =
1/2 [cos(a+b)+cos(a-b)]
35
sin(2a) =
2sin(a)cos(a)
36
cos(2a) =
cos^2(a)-sin^2(a)
37
