MATEMÁTICA III

Seja $\displaystyle{E}={s}{e}{n}{\left({x}+\pi\right)}+{2}{s}{e}{n}{\left({2}{x}\right)}-{3}{\cos{{\left(\frac{{x}}{{2}}\right)}}}-{\cos{{\left({x}\right)}}}$ . Para $\displaystyle{x}=\frac{{\pi}}{{3}}$ teremos E igual a:

$\displaystyle{1}+\frac{\sqrt{{3}}}{{2}}$
$\displaystyle-{\left(\frac{{1}}{{2}}+\sqrt{{3}}\right)}$
$\displaystyle\frac{{{2}\sqrt{{2}}-{1}}}{{2}}$
$\displaystyle-\frac{{1}}{{2}}+\sqrt{{2}}$
$\displaystyle-{1}-\sqrt{{2}}$
