Question

[29]Evaluate:2tan2450+cos2300–sin2600​

Answer 1

$\huge\sf \gray{q}{u} \gray{e}{s} \gray{t}{i} \gray{o}{n}$

$\bf{evaluate : } \\ \rm{2 \tan {}^{2}45 \degree + \cos {}^{2}30 \degree - \sin {}^{2} 60 \degree }$

$\huge \sf{a} \gray{n}{s} \gray{w}{e} \gray{r}$

$\tt{2 \times 1 + \frac{ \sqrt{ {3}^{2} } }{2} - \frac{ \sqrt{ {3}^{2} } }{2} }$

$\rm{by \: cutting \: both \: \frac{ \sqrt{ {3}^{2} } }{2} \: we \: get \: 1.}$

$\tt{2 \times 1 + 1 - 1} \\ \tt{2 \times 1 + 0} \\ \tt{2 + 0} \\ \tt{2}$
