### Valeurs remarquables | x | sin(x) | cos(x) | tan(x) | π | |---|---|---|---|---| | 0 | 0 | 1 | 0 | 0 | | π/6 | 1/2 | √3/2 | 1/√3 | 1 | | π/4 | √2/2 | √2/2 | 1 | 1 | | π/3 | √3/2 | 1/2 | √3 | 1 | | π/2 | 1 | 0 | ∞ | 0 | ### Relations Trigonométriques 1. cos (π/2 + x) = sin (x) = - sin x Les angles supplementaires ont meme sin et des signes opposes 2. Cos(π-x) = - cos(x) = -cos x Cos(π/2 - x) = cos(x) Cos(π/2 + x) = sin(x) Sin(π + x) = -sin x Cos(π + x) = -cos x ### Propriétés cos(a+b) = cosa cosb - sina sinb cos(a-b) = cosa cosb + sina sinb sin(a+b) = sina cosb + cosa sinb sin(a-b) = sina cosb - cosa sinb
