Nous nomont le calcule A

A =

[tex] \cos( \frac{5\pi}{8} ) [/tex]

A =

[tex] - \sqrt{ \frac{1 + \cos( \frac{5\pi}{4} ) }{2} } [/tex]

A =

[tex] - \sqrt{ \frac{1 - \frac{ \sqrt{2} }{2} }{2} } [/tex]

A =

[tex] - \sqrt{ \frac{ \frac{2 - \sqrt{2} }{2} }{2} } [/tex]

A =

[tex] - \sqrt{ \frac{2 - \sqrt{2} }{4} } [/tex]

A =

[tex] - \frac{ \sqrt{2 - \sqrt{2} } }{2} [/tex]

A =

[tex] = - 0. 38[/tex]
