Q

Cos (π/2 - x)

24
Q

Sin (π/2 - x)

25
Cos (π/2 + x)
- sin (x)
26
Sin (π/2 + x)
Cos (x)
27
Cos (x) = cos (a)
x = a + 2kπ, k E Z Ou x = -a + 2kπ, k E Z
28
Sin (x) = sin (a)
x = a +2kπ, k E Z Ou x = (π - a) + 2kπ, k E Z
29
u et v deux vecteurs non nuls, orthogonaux | (u, v) =
(u, v) = π/2 + kπ, k E Z
30
u, v et w trois vecteurs non nuls | (u, v) =
(u, v) = (u, w) + (w, v)
31
u et v deux vecteurs non nuls, on connaît u et v | (v, u) =
(v, u) = - (u, v)
32
u et v deux vecteurs non nuls, on connaît u et v | (u, - v) =
(u, - v) = (-u, v) = (u, v) + π
33
u et v deux vecteurs non nuls, on connaît u et v | (-u, -v) =
(-u, -v) = (u, v)
34
Cos² x + sin² x =
Cos² x + sin² x = 1
